Failure was discovered upon running projects/compiler-rt/test/builtins/Unit/divtc3_test.c in a stage2 compiler build. When compiling projects/compiler-rt/lib/builtins/divtc3.c, a call to fmaxl within the divtc3 implementation had its return values read from registers $2 and $3 instead of $f0 and $f2. Include fmaxl in the list of long double emulation routines to have its return value correctly interpreted as f128. Almost exact issue here: https://reviews.llvm.org/D17760 Differential Revision: https://reviews.llvm.org/D52649 llvm-svn: 344326
