This is a subsequent patch to refactor the existing float point vector comparison operator supports. The patch to fix PR92132 supplemented vector float point comparison by exposing the names for unordered/ordered/uneq/ltgt and adding ungt/unge/unlt/unle/ ne. As Segher pointed out, some patterns can be refactored together. The main link on this is: https://gcc.gnu.org/ml/gcc-patches/2019-11/msg00452.html gcc/ChangeLog 2019-11-25 Kewen Lin <linkw@gcc.gnu.org> * config/rs6000/vector.md (vector_fp_comparison_simple): New code iterator.

/bin/sh: :q: command not found This patch adds opt_for_fn for all cross module params used by inliner so they can be modified at function granuality. With inlining almost always there are three functions to consider (callee and caller of the inlined edge and the outer function caller is inlined to). I always use the outer function params since that is how local parameters behave. I hope it is kind of what is also expected in most case: it is better to inline agressively into -O3 compiled code rather than inline agressively -O3 functions into their callers. New params infrastructure is nice. One drawback is that is very hard to search for individual param uses since they all occupy global namespace. With C++ world we had chance to do something like params.param_flag_name or params::param_flag_name instead...

The tests amended here now have different code-gen with default options because, previously, the access were indirected per Darwin ABI for common accesses. The revised code-gen does not match the expected scan-asms because Darwin defaults to fPIC. For these tests, it seems that the best solution is to use '-mdynamic-no-pic' in the m32 case which makes the output similar to the ElF platform default. gcc/testsuite/ChangeLog: 2019-11-22 Iain Sandoe <iain@sandoe.co.uk> * gcc.target/i386/pr27971.c: Use mdynamic-no-pic for m32 on Darwin. * gcc.target/i386/sse2-load-multi.c: Likewise. * gcc.target/i386/sse2-store-multi.c: Likewise.
