xref: /llvm-project/llvm/test/tools/llvm-readobj/ELF/RISCV/attributes-invalid.test (revision 137a25f04a515e5ea8f24c897e34b4cd236239a8)

## Check how we dump invalid SHT_RISCV_ATTRIBUTES sections.

## This test case is used to ensure llvm-readobj checks the version of
## attribute sections correctly. The only supported format is 'A' (41),
## here we use 'B' (42).

# RUN: yaml2obj %s -D BITS=32 -DCONTENT=42 -o %t1.32.o
# RUN: llvm-readobj -A %t1.32.o 2>&1 | \
# RUN:   FileCheck -DFILE=%t1 %s --implicit-check-not=warning: --check-prefix=ERR-FORMAT
# RUN: yaml2obj %s -D BITS=64 -DCONTENT=42 -o %t1.64.o
# RUN: llvm-readobj -A %t1.64.o 2>&1 | \
# RUN:   FileCheck -DFILE=%t1 %s --implicit-check-not=warning: --check-prefix=ERR-FORMAT

# ERR-FORMAT:      BuildAttributes {
# ERR-FORMAT-NEXT:   FormatVersion: 0x42
# ERR-FORMAT-NEXT: warning: '[[FILE]].{{32|64}}.o': unable to dump attributes from the SHT_RISCV_ATTRIBUTES section with index 1: unrecognized format-version: 0x42
