8eb2d2b0	2020-02-24T10:29:20	Revamp PA_LINUX and PA_HPUX target closures to use function descriptors. 2020-02-23 John David Anglin <danglin@gcc.gnu.org> * include/ffi.h.in (FFI_CLOSURE_PTR, FFI_RESTORE_PTR): Define. * src/closures.c (ffi_closure_alloc): Convert closure pointer return by malloc to function pointer. (ffi_closure_free): Convert function pointer back to malloc pointer. * src/pa/ffi.c (ffi_closure_inner_pa32): Use union to double word align return address on stack. Adjust statements referencing return address. Convert closure argument from function pointer to standard closure pointer. (ffi_prep_closure_loc): Likewise convert closure argument back to closure pointer. Remove assembler trampolines. Setup simulated function descriptor as on ia64. src/pa/ffitarget.h (FFI_TRAMPOLINE_SIZE): Reduce to 12. src/pa/hpux32.S (ffi_closure_pa32): Retrieve closure pointer and real gp from fake gp value in register %r19. src/pa/linux.S (ffi_closure_pa32): Likewise.

Fixed TEXTREL by using pcrel (instead of ABS) encoding for absolute addresses (__PIC__ code) by adding augmentation information ("zR" CIE type). All tests still pass on hppa2.0.
