GCC compat testing and simulator question

2016-02-01 Thread Steve Ellcey
I have a question about the compatibility tests (gcc.dg/compat and g++.dg/compat). Do they work with remote/simulator testing? I was trying to run them with qemu and even though I am setting ALT_CC_UNDER_TEST and ALT_CXX_UNDER_TEST it doesn't look like my alternative compiler is ever getting run

Thanks Mikhail and Manuel for the reactions! Mikhail, thanks for the tip on xmalloc, will take a look if that can help clean up the plugin code. Manuel, 0) Yes, we hope to make it faster! 1) Initially coding within GCC would have been too intimidating, but I think i've started to get a feel for

Help about how to bootstrap gcc with local version glibc other than system one

2016-02-01 Thread Bin.Cheng
Hi, Recently I tried to bootstrap gcc against new glibc but failed. What I want to do is just bootstrap gcc against local version glibc other than system one, because I can't update glibc in that system. I tried this by configuring GCC using "--with-build-sysroot" or "--with-sysroot" or both, but
