Hi,
What is the correct syntax for conditional jumps (j<cc>) in GNU as when using intel syntax?Â
Specifically:
# This dummy example code does not assemble:
 .intel_syntax noprefix
L1:
 test eax,eax
 jnz L1
 ret
.....
%as test1.s Â
%test1.s:6:suffix or operands invalid for `jnz'
# This code (same but temp. switch to AT&T syntax) assembles correctly:
 .intel_syntax noprefix
L1:
 test eax,eax
.att_syntax
 jnz L1
.intel_syntax noprefix
 ret
% as test2.s Â
% otool -Vt test2.o
test2.o:
(__TEXT,__text) section
00000000 testl êx,êx
00000002 jne 0x00000000
00000004 ret
I'm using: Apple Inc version cctools-698.1~1, GNU assembler version 1.38
What's up??
LG
