llvm-addrsig-section.yaml 2.12 KB
## Check how obj2yaml dumps the SHT_LLVM_ADDRSIG section.

## Check that when possible obj2yaml tries to produce the "Name" tag when
## dumping entries of the SHT_LLVM_ADDRSIG section. It falls back to producing
## the "Index" tag when it can't match a symbol index with a symbol table entry.

# RUN: yaml2obj --docnum=1 %s -o %t1
# RUN: obj2yaml %t1 | FileCheck %s --check-prefix=NAME

## data using the "Content" tag when at least one of the entries is broken,
## e.g. because the entry contains a malformed uleb128 value.
