The binutils 2.18 for powerpc generate/output these codes: 10: 40 82 00 00 bne- 10 <atomic_modify+0x10> or 10: 40 a2 00 00 bne+ 10 <atomic_modify+0x10>
On IBM's website : http://publib.boulder.ibm.com/infocenter/systems/index.jsp?topic=/com.ibm.aix.aixassem/doc/alangref/about.htm&tocNode=int_378 I got these information: 40 a2 -> (0100 00)(00 1_01_)0 .... (in binutils, it's interpreated as bne+) 40 82 -> (0100 00)(00 1_00_)0 .... (in binutils, it's interpreated as bne-) Of which, the second group field is BO code, which means: 001at Branch if the condition is False. at field is(from IBM site, which apparently has an errata): at Hint 00 No hint is given. 01 Reserved 01 The branch is very likely not to be taken. 11 The branch is very likely to be taken. So, who's right? -- Summary: Wrongly interpretation of branch hint codes for powerpc Product: binutils Version: 2.18 Status: NEW Severity: normal Priority: P2 Component: binutils AssignedTo: unassigned at sources dot redhat dot com ReportedBy: hellwolf dot misty at gmail dot com CC: bug-binutils at gnu dot org http://sourceware.org/bugzilla/show_bug.cgi?id=7005 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
