## Show that the archive library emits error messages when adding malformed
## objects.

# RUN: rm -rf %t.dir
# RUN: split-file %s %t.dir
# RUN: cd %t.dir

## Malformed bitcode object is the first file member of archive if the symbol table is required.
# RUN: llvm-as input.ll -o input.bc
# RUN: cp input.bc good.bc
# RUN: %python -c "with open('input.bc', 'a') as f: f.truncate(10)"
# RUN: not llvm-ar rc bad.a input.bc 2>&1 | FileCheck %s --check-prefix=ERR1

## Malformed bitcode object is the last file member of archive if the symbol table is required.
# RUN: rm -rf bad.a
# RUN: not llvm-ar rc bad.a good.bc input.bc 2>&1 | FileCheck %s --check-prefix=ERR1

## Malformed bitcode object if the symbol table is not required for big archive.
# RUN: rm -rf bad.a
# RUN: not llvm-ar --format=bigarchive rcS bad.a input.bc 2>&1 | FileCheck %s --check-prefix=ERR1
# RUN: rm -rf bad.a
# RUN: not llvm-ar --format=bigarchive rcS bad.a good.bc input.bc 2>&1 | FileCheck %s --check-prefix=ERR1

# ERR1: error: bad.a: 'input.bc': Invalid bitcode signature

## Non-bitcode malformed file.
# RUN: yaml2obj input.yaml -o input.o

# ERR2: error: bad.a: 'input.o': section header table goes past the end of the file: e_shoff = 0x9999

## Don't emit an error if the symbol table is not required for formats other than the big archive format.
