--- Comment #6 from davem at gcc dot gnu.org 2012-05-02 07:01:24 UTC --- Created attachment 27283 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27283 Simplest test case. Build with -O1 -ffloat-store -m64 on sparc This is the most simplest test case which generates a long double soft-fp libcall on sparc64, and DSE erroneously eliminates the stores that setup the arguments.
