Zack Weinberg a053e87849 Remove support for PowerPC SPE extension (powerpc*-*-*gnuspe*). ... GCC 9 dropped support for the SPE extensions to PowerPC, which means powerpc*-*-*gnuspe* configurations are no longer buildable with that compiler. This ISA extension was peculiar to the “e500” line of embedded PowerPC chips, which, as far as I can tell, are no longer being manufactured, so I think we should follow suit. This patch was developed by grepping for “e500”, “__SPE__”, and “__NO_FPRS__”, and may not eliminate every vestige of SPE support. Most uses of __NO_FPRS__ are left alone, as they are relevant to normal embedded PowerPC with soft-float. * sysdeps/powerpc/preconfigure: Error out on powerpc-*-*gnuspe* host type. * scripts/build-many-glibcs.py: Remove powerpc-*-linux-gnuspe and powerpc-*-linux-gnuspe-e500v1 from list of build configurations. * sysdeps/powerpc/powerpc32/e500: Recursively delete. * sysdeps/unix/sysv/linux/powerpc/powerpc32/e500: Recursively delete. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/context-e500.h: Delete. * sysdeps/powerpc/fpu_control.h: Remove SPE variant. Issue an #error if used with a compiler in SPE-float mode. * sysdeps/powerpc/powerpc32/__longjmp_common.S * sysdeps/powerpc/powerpc32/setjmp_common.S * sysdeps/unix/sysv/linux/powerpc/powerpc32/getcontext-common.S * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/getcontext.S * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/setcontext.S * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/swapcontext.S * sysdeps/unix/sysv/linux/powerpc/powerpc32/setcontext-common.S * sysdeps/unix/sysv/linux/powerpc/powerpc32/swapcontext-common.S: Remove code to preserve SPE register state. * sysdeps/unix/sysv/linux/powerpc/elision-lock.c * sysdeps/unix/sysv/linux/powerpc/elision-trylock.c * sysdeps/unix/sysv/linux/powerpc/elision-unlock.c Remove __SPE__ ifndefs.		2019-05-22 10:05:40 -04:00
