[Bug c++/55544] -fexcess-precision=standard is not implemented for C++

2012-11-30 Thread joerg.rich...@pdv-fs.de
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=55544 --- Comment #5 from Jörg Richter 2012-11-30 13:47:24 UTC --- -ffloat-store works. But I dont want to use it in our project. -msse2 -mfpmath=sse does not work. I still see fildll,fnstcw,... instructions in the assembler listing.
