Bug ID: 25904
Summary: LLVM_CXXFLAGS is used without escaping quotes
Product: Build scripts
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: cmake
Assignee: unassignedb...@nondot.org
Reporter: jerem...@apple.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
I have updated our build system to add -DSVN_REVISION='"<revision>"' to
CXXFLAGS at configure-time when building clang in order to work around bug
#25681.
Unfortunately, does not work because it is added to the LLVM_CXXFLAGS macro
without escaping the quotes:
trunk/tools/llvm-config/llvm-config.cpp:441:45: error: expected ';' after
expression
OS << ActiveIncludeOption << ' ' << LLVM_CXXFLAGS << '\n';
^
build/tools/llvm-config/BuildVariables.inc:24:51: note: expanded from macro
'LLVM_CXXFLAGS'
#define LLVM_CXXFLAGS "-pipe -Os -DSVN_REVISION='"256125"' -std=c++11
-stdlib=libc++ -arch x86_64 -fPIC -fvisibility-inlines-hidden -Wall -W
-Wno-unused-parameter -Wwrite-strings -Wcast-qual -Wmissing-field-initializers
-pedantic -Wno-long-long -Wcovered-switch-default -Wnon-virtual-dtor
-Wdelete-non-virtual-dtor -std=c++11 -g -fno-exceptions
-D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS"
^
Whatever sets LLVM_CXXFLAGS in BuildVariables.inc should be sure to escape it
appropriately.
