test/tools/llvm-objcopy/ELF/wildcard-syntax.test

## This test checks that llvm-objcopy accepts glob (or "shell wildcard") syntax
## for the --wildcard (-w) flag correctly.

# RUN: yaml2obj --docnum=1 %s > %t.o

## * matches all characters.
# RUN: llvm-objcopy --remove-section='.f*' %t.o %t.glob.o
# RUN: llvm-readobj --sections %t.glob.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,BAR

## Glob matches are full matches. ("*a" does not match ".bar").
# RUN: llvm-objcopy --remove-section='*a' %t.o %t.full.o
# RUN: llvm-readobj --sections %t.full.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,FOO,BAR

## ? matches one character.
# RUN: llvm-objcopy --remove-section='.b?r' %t.o %t.question.o
# RUN: llvm-readobj --sections %t.question.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,FOO

## ! (as a leading character) prevents matches, and is not dependent on
## ordering.
# RUN: llvm-objcopy --remove-section='.???' --remove-section='!.f*' \
# RUN:   %t.o %t.negmatch1.o
# RUN: llvm-readobj --sections %t.negmatch1.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,FOO
# RUN: llvm-objcopy --remove-section='!.f*' --remove-section='.???' \
# RUN:   %t.o %t.negmatch2.o
# RUN: llvm-readobj --sections %t.negmatch2.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,FOO
# RUN: llvm-objcopy --remove-section='.???' --remove-section='!.f*' \
# RUN:   --remove-section='.???' %t.o %t.negmatch3.o
# RUN: llvm-readobj --sections %t.negmatch3.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,FOO

## [a-z] matches a range of characters.
# RUN: llvm-objcopy --remove-section='.[a-c][a-a][q-s]' %t.o %t.range.o
# RUN: llvm-readobj --sections %t.range.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,FOO

## [^a-z] or [!a-z] match a negated range of characters.
# RUN: llvm-objcopy --remove-section='.[^x]oo' %t.o %t.negrange.1.o
# RUN: llvm-readobj --sections %t.negrange.1.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,BAR
# RUN: llvm-objcopy --remove-section='.[!x]oo' %t.o %t.negrange.2.o
# RUN: llvm-readobj --sections %t.negrange.2.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: --check-prefixes=CHECK,BAR

## Use a separate test file with special characters for the following tests.

# RUN: yaml2obj --docnum=2 %s > %t.special.o

## \ escapes wildcard characters.
# RUN: llvm-objcopy --remove-section='\*' %t.special.o %t.escape.1.o

# RUN:   | FileCheck %s --implicit-check-not=Name: \

## Special characters in character classes are treated literally.
## [*] should not get expanded to [.*], which would match both '.' and '*'
# RUN: llvm-objcopy --remove-section='[*]' %t.special.o %t.class.1.o
# RUN: llvm-readobj --sections %t.class.1.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: \
# RUN:   --check-prefixes=CHECK,DOT,QUESTION,LEFT-BRACKET,RIGHT-BRACKET,INVALID-GLOB,Z,XYZ,FOO

## ] doesn't close the character class as a first character. This glob matches
## a single character which is one of ']xyz'. ']' and 'z' are removed, and more explicitly,
## section 'xyz]' is not removed, i.e. the glob is not interpreted as "an empty
## character class followed by 'xyz]'"
# RUN: llvm-objcopy --remove-section='[]xyz]' %t.special.o %t.class.2.o
# RUN: llvm-readobj --sections %t.class.2.o \
# RUN:   | FileCheck %s --implicit-check-not=Name: \
# RUN:   --check-prefixes=CHECK,DOT,ASTERISK,QUESTION,LEFT-BRACKET,INVALID-GLOB,XYZ,FOO

## An invalid glob expression is interpreted as a literal instead.
# RUN: llvm-objcopy --remove-section='][]' %t.special.o %t.class.3.o 2>&1 \
# RUN:   | FileCheck %s --check-prefix=WARN
# RUN: llvm-readobj --sections %t.class.3.o \
