show_bug.cgi?id=738 --- Comment #10 from Bob Moore <robert.moore(a)intel.com> 2009-08-25 09:09:29 --- iASL uses bison/flex to generate. I can build a windows version of iASL for you to try. I'm in the middle of rebuilding a crashed machine, so please be patient, it might take a day or so.

show_bug.cgi?id=738 --- Comment #9 from Sergiy <yakovlevs(a)ami.com> 2009-08-25 08:57:09 --- Dear Lin Ming Sorry for confusing you but I thought that first 2 lines of comment #6 was the patch: Scope(\_SB){ Name(PRSA, ResourceTemplate(){ // Link name: LNKA IRQ(Level, ActiveLow, Shared, LLKA) {3,4,5,6,7,10,11,12,14,15} Alias(PRSA,PRSB) // Link name: LNKB }) } Since it slightly different from what I have: In your comment #6, Alias term located inside the scope of the ResourceTemplate, In example I was giving it was outside. Scope(\_SB){ Name(PRSA, ResourceTemplate(){ // Link name: LNKA IRQ(Level, ActiveLow, Shared, LLKA) {3,4,5,6,7,10,11,12,14,15} }) Alias(PRSA,PRSB) // Link name: LNKB } Meanwhile I'm having some difficulty building ACPI CA components. I can't build the sources It is possible I'm missing some libraries or tools. I have VC 9 the project is for VC 6. So could you please build the version of iASL with that fix for me and attach *.exe file to this ISSUE tracker. Or send it directly to my email <yakovlevs(a)ami.com> with changed extension like iasl.ex_. I'll be happy to test it with my project.

show_bug.cgi?id=738 --- Comment #7 from Sergiy <yakovlevs(a)ami.com> 2009-08-24 07:55:25 --- The problem is that in my Project I'm using parts of ASL code generated By the tool we call VeB. The code I've used as example to report this bug was, unfortunately the one auto-generated. In this case workaround in ASL code will not help. We ar not going to modify the tool. Are you guys planing on fixing this bug generically in next revisions of iASL? I've tried: your fix it works, also I've tried using full relative name like Alias(\_SB.PRSA,PRSB) it also solves compilation problem. But this is not the fix for me. Could you tell me when to expect iASL with fix for this issue.

show_bug.cgi?id=738 --- Comment #6 from Ming Lin <ming.m.lin(a)intel.com> 2009-08-23 19:32:45 --- Created an attachment (id=841) --> (attachment.cgi?id=841) proposed patch Scope(\_SB){ Name(PRSA, ResourceTemplate(){ // Link name: LNKA IRQ(Level, ActiveLow, Shared, LLKA) {3,4,5,6,7,10,11,12,14,15} Alias(PRSA,PRSB) // Link name: LNKB }) } LdNamespace1Begin pushes ScopeInfo for _SB, PRSA, LLKA but LdNamespace2Begin only pushes ScopeInfo for _SB, _PRSA (no LLKA) 3 ScopeInfo pops in LdCommonNamespaceEnd, but only 2 ScopInfo pushes in LdNamespace2Begin. This causes AcpiNsLookup fails for "PRSA", because ScopInfo was popped. The attached one line patch fixes the bug. I tested it with ASLTS, it works. Sergiy, would you please help to test the patch?
