Has anybody else tried to get clang 3.5.0 running on a sparc64 box ??
I am not getting very far, make toolchain and buildworld is failing for
me on a 10.1-RELEASE (plus clang34) trying to build a clang350-import
src. Errors like;
/usr/src/lib/libc/../../include/pthread.h:197:7: error: expected
after function declarator
I am currently working with Roman Divacky on an out of tree llvm/clang
build, also failing at the moment with;
fatal error: error in backend: Invalid register name global variable
Has anyone replicated this, or (hopefully!!) got further ?
