Hi everyone.
Kindly find attached the files for reference, in the below steps :
- reproducer.c is the file which is being compiled.
- The variable under question is “testVar”, which has been initialized to 1, and thus ought to go in the .data section, irrespective.
- Upon compiling with -O0, testVar gets assigned to .data section, as expected.
-- ./do.sh -O0
-- Contents can be seen in dump_-O0
- Upon compiling with -O2, testVar gets assigned to .bss section, which is wrong.
-- ./do.sh -O2
-- Contents can be seen in dump_-O2
Have tested on LLVM/Clang 15, 17, 18, 19 - behaviour is identical.
Plus, the issue is not powerpc-specific; occurs even for x86 targets.
Long standing bug?
Thanks and Regards,
Ajay
