Subject: [PATCH] rs6000: Fix crash with big stack clash interval (PR82674)
If the user asks for a stack clash probe interval of 64kB, we currently
generate a "stdu rX,-65536(r1)" instruction. That instruction does not
exist (the offset is a 16-bit signed number). If the offset is too big
we should force it into a register and generate a "stdux rX,rY,r1"
instruction, instead.
PR target/82674
* config/rs6000/rs6000.md (allocate_stack): Force update interval
into a register if it does not fit into an immediate offset field.
