Fold single imm use of a FMA if it is a negation [PR95060]
match.pd already has simplifications for negation of a FMA (FMS, FNMA, FNMS) call if it is single use, but when the widening_mul pass discovers FMAs, nothing folds the statements anymore. So, the following patch adjusts the widening_mul pass to handle that. I had to adjust quite a lot of tests, because they have in them nested FMAs (one FMA feeding another one) and the patch results in some (equivalent) changes in the chosen instructions, previously the negation of one FMA's result would result in the dependent FMA being adjusted for the negation, but now instead the first FMA is adjusted. 2020-05-13 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/95060 * tree-ssa-math-opts.c (convert_mult_to_fma_1): Fold a NEGATE_EXPR if it is the single use of the FMA internal builtin. * gcc.target/i386/avx512f-pr95060.c: New test. * gcc.target/i386/fma_double_1.c: Adjust expected insn counts. * gcc.target/i386/fma_double_2.c: Likewise. * gcc.target/i386/fma_double_3.c: Likewise. * gcc.target/i386/fma_double_4.c: Likewise. * gcc.target/i386/fma_double_5.c: Likewise. * gcc.target/i386/fma_double_6.c: Likewise. * gcc.target/i386/fma_float_1.c: Likewise. * gcc.target/i386/fma_float_2.c: Likewise. * gcc.target/i386/fma_float_3.c: Likewise. * gcc.target/i386/fma_float_4.c: Likewise. * gcc.target/i386/fma_float_5.c: Likewise. * gcc.target/i386/fma_float_6.c: Likewise. * gcc.target/i386/l_fma_double_1.c: Likewise. * gcc.target/i386/l_fma_double_2.c: Likewise. * gcc.target/i386/l_fma_double_3.c: Likewise. * gcc.target/i386/l_fma_double_4.c: Likewise. * gcc.target/i386/l_fma_double_5.c: Likewise. * gcc.target/i386/l_fma_double_6.c: Likewise. * gcc.target/i386/l_fma_float_1.c: Likewise. * gcc.target/i386/l_fma_float_2.c: Likewise. * gcc.target/i386/l_fma_float_3.c: Likewise. * gcc.target/i386/l_fma_float_4.c: Likewise. * gcc.target/i386/l_fma_float_5.c: Likewise. * gcc.target/i386/l_fma_float_6.c: Likewise.
