Re: Bootstrap comparison failure on powerpc64 for Ada
Maybe the problem will arise on other platforms and we'll be able to debug it. SPARC/Solaris 32-bit is OK. I'm going to try the 64-bit variant. -- Eric Botcazou
Re: Bootstrap comparison failure on powerpc64 for Ada
I'm going to try the 64-bit variant. SPARC/Solaris 64-bit is OK, as well as IA-64/Linux according to: http://gcc.gnu.org/ml/gcc-testresults/2007-06/msg01044.html Do you test PowerPC 32-bit or should I try a build on Darwin or AIX? -- Eric Botcazou

Which revision? The Ada compiler bootstraps fine on i586 and x86-64 at revision 125912:125915M (i.e with structural alias analysis enabled). revision 125915. Thanks, Revital

Note that if cc1-checksum.o differs, it likely means the issue is unrelated to Ada. I am now bootstrapping only c. If that will pass OK I can check Ada on an older revision if you wish. Revital Arno

Re: Bootstrap comparison failure on powerpc64 for Ada
I am now bootstrapping only c. If that will pass OK I can check Ada on an older revision if you wish. I'm not sure that would really help in this case. The fact that x86 and x86-64 are both clean with structural alias analysis would seem to show that there is no fundamental bad interaction between it and Ada anymore. We cannot really debug on PowerPC 64-bit so I'd suggest to disable Ada in your builds for the time being (unless you have the time to investigate yourself). Maybe the problem will arise on other platforms and we'll be able to debug it. -- Eric Botcazou
