wildcard-flags.test 6.26 KB
## This test checks basic functionality of glob (or "shell wildcard") matching,
## as well as verifying all the relevant flags in llvm-objcopy and llvm-strip
## are configured correctly.
## For more detailed syntax tests, see wildcard-syntax.test.

# RUN: yaml2obj %s -o %t.o

## Check that --regex and --wildcard cannot be used together.
# RUN: not llvm-objcopy --regex --wildcard %t.o %t.err.o 2>&1 \
# RUN:   | FileCheck %s --check-prefix=ERR
# RUN: not llvm-strip --regex --wildcard %t.o -o %t.err.o 2>&1 \
# RUN:   | FileCheck %s --check-prefix=ERR

# ERR: error: --regex and --wildcard are incompatible

## Check that section removal flags default to glob matches.

## --keep-section:
# RUN: llvm-objcopy --strip-all --keep-section='.f*' %t.o %t.ksec.1.o
# RUN: llvm-readobj --sections %t.ksec.1.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,SEC,FOO-SEC

# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,SEC,FOO-SEC

# RUN: llvm-strip --strip-debug --remove-section='.s??tab' %t.o -o %t.rsec.2.o
# RUN: cmp %t.rsec.1.o %t.rsec.2.o

## Check that symbol removal options default to literal matches. Adding -w
## enables glob support for these options.
