| # RUN: yaml2obj %s -o %t |
| |
| ## The binary used in this test can be built (on OSX) as follows: |
| ## main.c: |
| ## __attribute__((used)) static int a[1021]; |
| ## __attribute__((used)) static char b = 1; |
| ## int main() { |
| ## return 0; |
| ## } |
| ## build command: |
| ## clang -fno-exceptions -fno-unwind-tables main.c -o main.exe |
| ## Note, that the variable "b" (whose size is 1) is placed into __DATA,__data section, |
| ## the array "a" (whose size is 4 * 1021 = 4084) is placed into __DATA,__bss and |
| ## __DATA,__bss is 16-byte aligned. In this case the total vmsize narrowly crosses |
| ## the border of one page (4096) and the final value should be equal to 8192. |
| |
| # RUN: llvm-objcopy %t %t.copy |
| # RUN: cmp %t %t.copy |
| |
| ## This additionally verifies that the binary created by llvm-objcopy/yaml2obj is valid. |
| # RUN: llvm-readobj --sections %t.copy |
