Compiling libF77/c_log.c with -O2 -m4-single produces:
!(insn 120 129 176 (parallel[
! (set (mem/s:SF (pre_dec:SI (reg/v/f:SI 8 r8 [54])) 3)
! (reg:SF 22 fpul [87]))
! (use (reg/v:PSI 48 fpscr))
! (clobber (scratch:SI))
! ] ) 91 {movsf_ie} (insn_list 118 (insn_list:REG_DEP_ANTI 73 (insn_list 15 (insn_list:REG_DEP_ANTI 113 (insn_list 174 (nil))))))
! (expr_list:REG_DEAD (reg/v:PSI 48 fpscr)
! (expr_list:REG_DEAD (reg:SF 22 fpul [87])
! (expr_list:REG_UNUSED (scratch:SI)
! (expr_list:REG_UNUSED (reg/v/f:SI 8 r8 [54])
! (expr_list:REG_INC (reg/v/f:SI 8 r8 [54])
! (nil)))))))
sts fpul,@-r8 ! 120 movsf_ie/15 [length = 2]
which the assembler rejects with:
c_log.s:462: Error: invalid operands for opcode
I suspect it's related to:
2001-02-07 Alexandre Oliva <aoliva@redhat.com>
* config/sh/sh.md (reload_outsf): Removed.
(movsf_ie): Introduce constraints for FPUL loads and stores.
(reload_insf): Broaden the output constraint.
I'm assuming the problem is the asm template for movsf_ie.
Unfortunately I don't speak sh assembler.
