https://bugs.freedesktop.org/show_bug.cgi?id=47201 Bug #: 47201 Summary: TGSI source register with absolute negative modifier does not work correctly Classification: Unclassified Product: Mesa Version: 8.0 Platform: Other OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel@xxxxxxxxxxxxxxxxxxxxx ReportedBy: llyzs@xxxxxxx Recently I found a TGSI fragment shader does not render correctly with r600 driver and I further identified the issue down to instructions in this form: CMP TEMP[0].yz, -|TEMP[1].xxxx|, TEMP[2].xxxx, CONST[0].xyxw If I covert all those instructions to the equivalents: ABS TEMP[5], TEMP[1].xxxx CMP TEMP[0].yz, -TEMP[5], TEMP[2].xxxx, CONST[0].xyxw It then works fine. However, the original instructions work just fine with nouveau and swrast driver, so it should be a r600 bug. Any clue on this issue? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
