PR71175 reports two printf-style format/argument mismatches in the arm
backend, found by static analysis:
- arm_elf_asm_cdtor prints the int PRIORITY argument with %.5u; cast it
to unsigned int to match the format (constructor priorities are
restricted to [0, 65535] by the front ends, so the value is
unchanged).
- arm_unwind_emit_sequence prints the unsigned PADFIRST with %d; print
it with %u instead.
No change in generated code.
gcc/ChangeLog:
PR target/71175
* config/arm/arm.cc (arm_elf_asm_cdtor): Cast priority to
unsigned int to match the %.5u format.
(arm_unwind_emit_sequence): Print unsigned padfirst with %u
rather than %d.
