Error description
A simple inline ASM branch instruction to a label is causing a compile-time assembler error. ===== TEST CASE ===== int main() { int test; asm(" li %0,0 \n" " bc 7,27,1f \n" " li %0,1 \n" "1: \n" : "=r"(test) ); } $ xlc test.c Assembler: test$1.s: line 49: 1252-142 Syntax error. 1500-067:(S) asm statement generates errors in assembler output. $ The generated intermediate 'test$1.s' assembler file contains the following processed inline ASM: +48 li 0,0 +49 bc 7,27,1f +50 li 0,1 +51 .LL1_0: The '1f' branch label is not processed correctly, causing the assembler syntax error.
Local fix
- Add a space character between the comma and label in the inline ASM branch instruction - Use a label that does not begin with a digit character
Problem summary
USERS AFFECTED: Users writing inline ASM using local labels.
Problem conclusion
The compiler was corrected to support local labels next to comma characters.
Temporary fix
