Hi all, I propose to mark powerpc*-*-*spe* as obsolete in GCC 7. This includes the spe.h installed header file, all the __builtin_spe* intrinsics, the -mfloat-gprs= command-line option, and the support for the SPE ABIs.
No one has properly tested these targets in a long time (the latest testresults I could find are from July 2015, >1000 failures), and the SPE support makes a lot of code much more complex. Any objections to this obsoletion? GCC 7 will then be the last release with support for SPE (it will need --enable-obsolete to build these targets), and we will delete the SPE support during GCC 8 development. Segher
