I ran LTO for spu-elf. Most of the gcc.dg/lto.exp fail because -shared is not support as there are no shared library support for SPU yet. In fact there is an error running the lto.exp testsuite from dejagnu: +ERROR: tcl error sourcing /home/apinski/src/lto/gcc/gcc/testsuite/gcc.dg/lto/lto.exp. +ERROR: can't read "name": no such variable This is because 20081212-1 fails to link and we are still trying to do scan-symbol.
In the G++ testsuite, we have other issues. With -fPIC, GCC defaults to erroring out if there is a runtime relocation will happen, which causes some of the testcases to fail. And one ICE: +FAIL: g++.dg/lto/20090311 cp_lto_20090311_0.o-cp_lto_20090311_1.o link, (internal compiler error) lto1: internal compiler error: in duplicate_node_data, at ipa-pure-const.c:633^M This is at -O2 -flto . A link error: FAIL: g++.dg/lto/20090311 cp_lto_20090311_0.o-cp_lto_20090311_1.o link cp_lto_20090311_1.wpa.ltrans.o:(.rodata._ZTV2C2[_ZTV2C2]+0x8): undefined reference to `_ZN2C2D1Ev'^Mcollect2: ld returned 1 exit status^M This is at -O2 -fwhopr. Other than those issues, the results look like the trunk with addition failures at -O2 -flto which also happen at -O2. One failure without LTO which looks like it was introduced in just recently (between revision 152285 and 152343): FAIL: g++.dg/eh/crossjump1.C (test for excess errors) I almost want to say 2009-09-30 Diego Novillo <dnovi...@google.com> 2009-09-30 Diego Novillo <dnovi...@google.com> + + * cp/tree.c (cp_free_lang_data): Assert that DECL is a + FUNCTION_DECL or a VAR_DECL. + Call uses_template_params and check for + DECL_TEMPLATE_INSTANTIATION or + DECL_TEMPLATE_SPECIALIZATION introduced it. As I tested spu-elf before that patch without lto enabled and that testcase worked. As an aside looks like the testsuite link line does not record the optimization level which was used which means there might be a couple of the "tests" with the same name. Thanks, Andrew Pinski
