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.
the SPE unit is still used in the embedded PowerPC processors from
Freescale/NXP/Qualcomm, for example QorIQ P1020. These products are not
obsolete or even not recommended for new designs. These chips have a
long product life-cycle.
Its a pity that Freescale/NXP/Qualcomm stopped to support GCC
development and IBM is burdened to take care of this. I can understand
your reasoning, however, its not true that there are no users of the SPE
unit.
