# RUN: yaml2obj %s -o %t

## 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.)
