| |
| Changes in 2.13: |
| |
| Support for the Fujitsu FRV architecture added by Red Hat. Models for FR400 and |
| FR500 included. |
| |
| Support for DLX processor added. |
| |
| GASP has now been deprecated and will be removed in a future release. Use the |
| macro facilities in GAS instead. |
| |
| GASP now correctly parses floating point numbers. Unless the base is explicitly |
| specified, they are interpreted as decimal numbers regardless of the currently |
| specified base. |
| |
| Changes in 2.12: |
| |
| Support for Don Knuth's MMIX, by Hans-Peter Nilsson. |
| |
| Support for the OpenRISC 32-bit embedded processor by OpenCores. |
| |
| The ARM assembler now accepts -march=..., -mcpu=... and -mfpu=... for |
| specifying the target instruction set. The old method of specifying the |
| target processor has been deprecated, but is still accepted for |
| compatibility. |
| |
| Support for the VFP floating-point instruction set has been added to |
| the ARM assembler. |
| |
| New psuedo op: .incbin to include a set of binary data at a given point |
| in the assembly. Contributed by Anders Norlander. |
| |
| The MIPS assembler now accepts -march/-mtune. -mcpu has been deprecated |
| but still works for compatability. |
| |
| The MIPS assembler no longer issues a warning by default when it |
| generates a nop instruction from a macro. The new command line option |
| -n will turn on the warning. |
| |
| Changes in 2.11: |
| |
| x86 gas now supports the full Pentium4 instruction set. |
| |
| Support for AMD x86-64 architecture, by Jan Hubicka, SuSE Labs. |
| |
| Support for Motorola 68HC11 and 68HC12. |
| |
| Support for Texas Instruments TMS320C54x (tic54x). |
| |
| Support for IA-64. |
| |
| Support for i860, by Jason Eckhardt. |
| |
| Support for CRIS (Axis Communications ETRAX series). |
| |
| x86 gas has a new .arch pseudo op to specify the target CPU architecture. |
| |
| x86 gas -q command line option quietens warnings about register size changes |
| due to suffix, indirect jmp/call without `*', stand-alone prefixes, and |
| translating various deprecated floating point instructions. |
| |
| Changes in 2.10: |
| |
| Support for the ARM msr instruction was changed to only allow an immediate |
| operand when altering the flags field. |
| |
| Support for ATMEL AVR. |
| |
| Support for IBM 370 ELF. Somewhat experimental. |
| |
| Support for numbers with suffixes. |
| |
| Added support for breaking to the end of repeat loops. |
| |
| Added support for parallel instruction syntax (DOUBLEBAR_PARALLEL). |
| |
| New .elseif pseudo-op added. |
| |
| New --fatal-warnings option. |
| |
| picoJava architecture support added. |
| |
| Motorola MCore 210 processor support added. |
| |
| A new pseudo-op .intel_syntax has been implemented to allow gas to parse i386 |
| assembly programs with intel syntax. |
| |
| New pseudo-ops .func,.endfunc to aid in debugging user-written assembler code. |
| |
| Added -gdwarf2 option to generate DWARF 2 debugging information. |
| |
| Full 16-bit mode support for i386. |
| |
| Greatly improved instruction operand checking for i386. This change will |
| produce errors or warnings on incorrect assembly code that previous versions of |
| gas accepted. If you get unexpected messages from code that worked with older |
| versions of gas, please double check the code before reporting a bug. |
| |
| Weak symbol support added for COFF targets. |
| |
| Mitsubishi D30V support added. |
| |
| Texas Instruments c80 (tms320c80) support added. |
| |
| i960 ELF support added. |
| |
| ARM ELF support added. |
| |
| Changes in 2.9: |
| |
| Texas Instruments c30 (tms320c30) support added. |
| |
| The assembler now optimizes the exception frame information generated by egcs |
| and gcc 2.8. The new --traditional-format option disables this optimization. |
| |
| Added --gstabs option to generate stabs debugging information. |
| |
| The -a option takes a new suboption, m (e.g., -alm) to expand macros in a |
| listing. |
| |
| Added -MD option to print dependencies. |
| |
| Changes in 2.8: |
| |
| BeOS support added. |
| |
| MIPS16 support added. |
| |
| Motorola ColdFire 5200 support added (configure for m68k and use -m5200). |
| |
| Alpha/VMS support added. |
| |
| m68k options --base-size-default-16, --base-size-default-32, |
| --disp-size-default-16, and --disp-size-default-32 added. |
| |
| The alignment directives now take an optional third argument, which is the |
| maximum number of bytes to skip. If doing the alignment would require skipping |
| more than the given number of bytes, the alignment is not done at all. |
| |
| The ELF assembler has a new pseudo-op, .symver, used for symbol versioning. |
| |
| The -a option takes a new suboption, c (e.g., -alc), to skip false conditionals |
| in listings. |
| |
| Added new pseudo-op, .equiv; it's like .equ, except that it is an error if the |
| symbol is already defined. |
| |
| Changes in 2.7: |
| |
| The PowerPC assembler now allows the use of symbolic register names (r0, etc.) |
| if -mregnames is used. Symbolic names preceded by a '%' (%r0, etc.) can be |
| used any time. PowerPC 860 move to/from SPR instructions have been added. |
| |
| Alpha Linux (ELF) support added. |
| |
| PowerPC ELF support added. |
| |
| m68k Linux (ELF) support added. |
| |
| i960 Hx/Jx support added. |
| |
| i386/PowerPC gnu-win32 support added. |
| |
| SCO ELF support added. For OpenServer 5 targets (i386-unknown-sco3.2v5) the |
| default is to build COFF-only support. To get a set of tools that generate ELF |
| (they'll understand both COFF and ELF), you must configure with |
| target=i386-unknown-sco3.2v5elf. |
| |
| m88k-motorola-sysv3* support added. |
| |
| Changes in 2.6: |
| |
| Gas now directly supports macros, without requiring GASP. |
| |
| Gas now has an MRI assembler compatibility mode. Use -M or --mri to select MRI |
| mode. The pseudo-op ``.mri 1'' will switch into the MRI mode until the ``.mri |
| 0'' is seen; this can be convenient for inline assembler code. |
| |
| Added --defsym SYM=VALUE option. |
| |
| Added -mips4 support to MIPS assembler. |
| |
| Added PIC support to Solaris and SPARC SunOS 4 assembler. |
| |
| Changes in 2.4: |
| |
| Converted this directory to use an autoconf-generated configure script. |
| |
| ARM support, from Richard Earnshaw. |
| |
| Updated VMS support, from Pat Rankin, including considerably improved debugging |
| support. |
| |
| Support for the control registers in the 68060. |
| |
| Handles (ignores) a new directive ".this_GCC_requires_the_GNU_assembler", to |
| provide for possible future gcc changes, for targets where gas provides some |
| features not available in the native assembler. If the native assembler is |
| used, it should become obvious pretty quickly what the problem is. |
| |
| Usage message is available with "--help". |
| |
| The GNU Assembler Preprocessor (gasp) is included. (Actually, it was in 2.3 |
| also, but didn't get into the NEWS file.) |
| |
| Weak symbol support for a.out. |
| |
| A bug in the listing code which could cause an infinite loop has been fixed. |
| Bugs in listings when generating a COFF object file have also been fixed. |
| |
| Initial i386-svr4 PIC implementation from Eric Youngdale, based on code by Paul |
| Kranenburg. |
| |
| Improved Alpha support. Immediate constants can have a much larger range now. |
| Support for the 21164 has been contributed by Digital. |
| |
| Updated ns32k (pc532-mach, netbsd532) support from Ian Dall. |
| |
| Changes in 2.3: |
| |
| Mach i386 support, by David Mackenzie and Ken Raeburn. |
| |
| RS/6000 and PowerPC support by Ian Taylor. |
| |
| VMS command scripts (make-gas.com, config-gas.com) have been worked on a bit, |
| based on mail received from various people. The `-h#' option should work again |
| too. |
| |
| HP-PA work, by Jeff Law. Note, for the PA, gas-2.3 has been designed to work |
| with gdb-4.12 and gcc-2.6. As gcc-2.6 has not been released yet, a special |
| version of gcc-2.5.8 has been patched to work with gas-2.3. You can retrieve |
| this special version of gcc-2.5.8 via anonymous ftp from jaguar.cs.utah.edu |
| in the "dist" directory. |
| |
| Vax support in gas fixed for BSD, so it builds and seems to run a couple simple |
| tests okay. I haven't put it through extensive testing. (GNU make is |
| currently required for BSD 4.3 builds.) |
| |
| Support for the DEC Alpha, running OSF/1 (ECOFF format). The gas support is |
| based on code donated by CMU, which used an a.out-based format. I'm afraid the |
| alpha-a.out support is pretty badly mangled, and much of it removed; making it |
| work will require rewriting it as BFD support for the format anyways. |
| |
| Irix 5 support. |
| |
| The test suites have been fixed up a bit, so that they should work with a |
| couple different versions of expect and dejagnu. |
| |
| Symbols' values are now handled internally as expressions, permitting more |
| flexibility in evaluating them in some cases. Some details of relocation |
| handling have also changed, and simple constant pool management has been added, |
| to make the Alpha port easier. |
| |
| New option "--statistics" for printing out program run times. This is intended |
| to be used with the gcc "-Q" option, which prints out times spent in various |
| phases of compilation. (You should be able to get all of them printed out with |
| "gcc -Q -Wa,--statistics", I think.) |
| |
| ---------------------------------------------------------------- |
| |
| Changes in 2.2: |
| |
| RS/6000 AIX and MIPS SGI Irix 5 support has been added. |
| |
| Configurations that are still in development (and therefore are convenient to |
| have listed in configure.in) still get rejected without a minor change to |
| gas/Makefile.in, so people not doing development work shouldn't get the |
| impression that support for such configurations is actually believed to be |
| reliable. |
| |
| The program name (usually "as") is printed when a fatal error message is |
| displayed. This should prevent some confusion about the source of occasional |
| messages about "internal errors". |
| |
| ELF support is falling into place. Support for the 386 should be working. |
| Support for SPARC Solaris is in. HPPA support from Utah is being integrated. |
| |
| Symbol values are maintained as expressions instead of being immediately boiled |
| down to add-symbol, sub-symbol, and constant. This permits slightly more |
| complex calculations involving symbols whose values are not alreadey known. |
| |
| DBX-style debugging info ("stabs") is now supported for COFF formats. |
| If any stabs directives are seen in the source, GAS will create two new |
| sections: a ".stab" and a ".stabstr" section. The format of the .stab |
| section is nearly identical to the a.out symbol format, and .stabstr is |
| its string table. For this to be useful, you must have configured GCC |
| to generate stabs (by defining DBX_DEBUGGING_INFO), and must have a GDB |
| that can use the stab sections (4.11 or later). |
| |
| LynxOS, on i386 and m68k platforms, is now supported. SPARC LynxOS |
| support is in progress. |
| |
| ---------------------------------------------------------------- |
| |
| Changes in 2.1: |
| |
| Several small fixes for i386-aix (PS/2) support from Minh Tran-Le have been |
| incorporated, but not well tested yet. |
| |
| Altered the opcode table split for m68k; it should require less VM to compile |
| with gcc now. |
| |
| Some minor adjustments to add (Convergent Technologies') Miniframe support, |
| suggested by Ronald Cole. |
| |
| HPPA support (running OSF only, not HPUX) has been contributed by Utah. This |
| includes improved ELF support, which I've started adapting for SPARC Solaris |
| 2.x. Integration isn't completely, so it probably won't work. |
| |
| HP9000/300 support, donated by HP, has been merged in. |
| |
| Ian Taylor has finished the MIPS ECOFF (Ultrix, Irix) support. |
| |
| Better error messages for unsupported configurations (e.g., hppa-hpux). |
| |
| Test suite framework is starting to become reasonable. |
| |
| ---------------------------------------------------------------- |
| |
| Changes in 2.0: |
| |
| Mostly bug fixes. |
| |
| Some more merging of BFD and ELF code, but ELF still doesn't work. |
| |
| ---------------------------------------------------------------- |
| |
| Changes in 1.94: |
| |
| BFD merge is partly done. Adventurous souls may try giving configure the |
| "--with-bfd-assembler" option. Currently, ELF format requires it, a.out format |
| accepts it; SPARC CPU accepts it. It's the default only for OS "elf" or |
| "solaris". (ELF isn't really supported yet. It needs work. I've got some |
| code from Utah for HP-PA ELF, and from DG for m88k ELF, but they're not fully |
| merged yet.) |
| |
| The 68K opcode table has been split in half. It should now compile under gcc |
| without consuming ridiculous amounts of memory. |
| |
| A couple data structures have been reduced in size. This should result in |
| saving a little bit of space at runtime. |
| |
| Support for MIPS, from OSF and Ralph Campbell, has been merged in. The OSF |
| code provided ROSE format support, which I haven't merged in yet. (I can make |
| it available, if anyone wants to try it out.) Ralph's code, for BSD 4.4, |
| supports a.out format. We don't have ECOFF support in just yet; it's coming. |
| |
| Support for the Hitachi H8/500 has been added. |
| |
| VMS host and target support should be working now, thanks chiefly to Eric |
| Youngdale. |
| |
| ---------------------------------------------------------------- |
| |
| Changes in 1.93.01: |
| |
| For m68k, support for more processors has been added: 68040, CPU32, 68851. |
| |
| For i386, .align is now power-of-two; was number-of-bytes. |
| |
| For m68k, "%" is now accepted before register names. For COFF format, which |
| doesn't use underscore prefixes for C labels, it is required, so variable "a0" |
| can be distinguished from the register. |
| |
| Last public release was 1.38. Lots of configuration changes since then, lots |
| of new CPUs and formats, lots of bugs fixed. |
