| ## When targetting non-x86_64, the "large" flag is not allowed: |
| # RUN: not llvm-objcopy -O elf64-tradbigmips --set-section-flags=.foo=large %t %t.mips.large 2>&1 | FileCheck %s --check-prefixes=BAD-LARGE |
| # BAD-LARGE: error: {{.*}}: section flag SHF_X86_64_LARGE can only be used with x86_64 architecture |
| |
| ## Converting x86_64 to non-x86_64 preserves the flag equivalent to SHF_X86_64_LARGE. |
| ## (This is not a deliberate feature, but it reflects how preservation/setting of flags |
| ## works for arch-specific flags.) |
| # RUN: llvm-objcopy -O elf64-tradbigmips --set-section-flags=.foo=alloc --set-section-flags=.bar=alloc %t %t.mips |
| # RUN: llvm-readobj --sections %t.mips | FileCheck %s --check-prefixes=CHECK,REINTERPRET-GPREL |
| |
| ## Converting non-x86_64 to x86_64 clears the flag equivalent to SHF_X86_64_LARGE, |
| ## and SHF_X86_64_LARGE is set according to the presence of the "large" flag, |
| ## as long as --set-section-flags is used. If --set-section-flag is _not_ used, then |
| ## the section flag is retained. (This latter behaviour is also not deliberate.) |
