<pre>It seems like clang has some specific behavior when dealing with .macros
defined inside of inline asm. Given the following example:
# cat snip.c
int main(void)
{
asm ( ".macro FOO\n.endm" );
asm ( ".macro FOO\n.endm" );
}
# clang -o snip snip.c
# clang -no-integrated-as -o snip snip.c
/tmp/snip-a5a133.s: Assembler messages:
/tmp/snip-a5a133.s:19: Error: Macro `foo' was already defined
clang: error: assembler command failed with exit code 1 (use -v to see
invocation)
Would it be possible to fix clang so it keeps .macro-s defined in other asm()-s
on the same compilation unit? (ie: so that it has the same behavior as gnu as)
Thanks, Roger.</pre>
