and "message" pragmas
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: unassignedclangb...@nondot.org
Reporter: andrey.kules...@intel.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
!- clang does not recognize macros __FUNCTION__ and __FUNCDNAME__ in #pragma
message and #pragma comment. Ms cl compiler works without errors and prints
function name in this case -!
===========ENVIRONMENT==================
OS: Windows
Language: c/c++
Version: trunk
===========SMALL REPRODUCER=============
void func(void) {
#pragma message(__FUNCTION__)
#pragma message("function = " __FUNCTION__)
#pragma message("function = " "WHY_NOT" __FUNCTION__ "\n")
#pragma comment(linker, "/EXPORT:" __FUNCTION__ "=" __FUNCDNAME__)
#pragma message("/EXPORT:" __FUNCTION__ "=" __FUNCDNAME__)
}
============DIAGNOSTICS==================
>>>clang:
test.cpp:2:19: error: expected string literal in pragma message
#pragma message(__FUNCTION__)
test.cpp:3:33: error: pragma message requires parenthesized string
#pragma message("function = " __FUNCTION__)
test.cpp:4:43: error: pragma message requires parenthesized string
#pragma message("function = " "WHY_NOT" __FUNCTION__ "\n")
test.cpp:5:38: error: pragma comment requires parenthesized identifier and
optional string
#pragma comment(linker, "/EXPORT:" __FUNCTION__ "=" __FUNCDNAME__)
test.cpp:6:30: error: pragma message requires parenthesized string
#pragma message("/EXPORT:" __FUNCTION__ "=" __FUNCDNAME__)
