[Bug 20922] New: Wine generates invalid ARB vertex programs
http://bugs.winehq.org/show_bug.cgi?id=20922 Summary: Wine generates invalid ARB vertex programs Product: Wine Version: 1.1.34 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d AssignedTo: wine-bugs(a)winehq.org ReportedBy: m.cencora(a)gmail.com Created an attachment (id=25082) --> (http://bugs.winehq.org/attachment.cgi?id=25082) Assassin's Creed game output, the bad program starts at line 979 When emulating sin/cos instructions in vertex programs, lines like these are created: MUL TA.x, R0.x, C4.w.w; MAD TA.x, TA.y, C4.w.x, TA.x; The problem is the double swizzle (i.e. C4.w.w C4.w.x). -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I suspect that the input shader is already incorrect. src1 and src2 - where the double swizzle occurs - are supposed to be 4 component constant registers. The double swizzle occurs because the app sets a swizzle on src1 and src2(2nd and third param) and the shader_addline code simply concatenates ".w" without looking at the input swizzle. The question is if it should. C4.w is a single scalar, it can't possibly work with what the helper constants are supposed to do. I'll have to write a test case to figure out how Wine is supposed to behave here. I suspect we should reject the shader and return an error when the app tries to create it. Its also possible that we should simply ignore the swizzle and treat "C4.w" as "C4" in this specific instruction. Or, maybe we should honor the swizzle and return incorrect results because the taylor coefficients aren't correct. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
