Summary: clang __gnu_inline__ semantics do not match gcc
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: OpenBSD
Status: NEW
Severity: normal
Priority: P2
Component: new bugs

int foo(void);
extern inline __attribute__((__gnu_inline__)) int
foo(void)
{
return 5;
}
int
main(int argc, char *argv[])
{
foo();
return (0);
}
will cause a symbol to be generated with clang if the prototype aka "int
foo(void);" is present.
ie
# nm foo.o
00000000 T foo
00000000 F foo.c
00000020 T main
if the prototype isn't present then a symbol isn't generated.
# nm foo.o
U foo
00000000 F foo.c
00000000 T main
gcc 4.2.4 will apparently never create a symbol in both cases:
# nm foo.o
U foo
00000000 F foo.c
00000000 T main
