- mem = gen_rtx_MEM (Pmode, plus_constant (Pmode, operands[0],
- 3 * GET_MODE_SIZE (Pmode)));
- reg_ssp = gen_reg_rtx (Pmode);
+ mem = gen_rtx_MEM (word_mode, plus_constant (Pmode, operands[0],
+ 3 * GET_MODE_SIZE (Pmode)));
The first 3 fields are SP, FP and IP, which are in ptr_mode, not Pmode.
/* Compute the numebr of frames to adjust. */
+ reg_adj = gen_rtx_SUBREG (Pmode, reg_ssp, 0);
reg_ssp must be in word_mode, not in Pmode.
Please show the assembly outputs of __builtin_setjmp and __builtin_longjmp
with the updated patch.
