Hi Andrew,
The PCS IHI0056C defines SIZE_TYPE as 'unsigned long' for both ILP32
and LP64 and PTRDIFF_TYPE as "signed long" for both ILP32 and LP64.
This seems like a sane choice to me.
Trying to recreate the failure with the test fragment above doesn't
given a warning:
$ aarch64-none-elf-gcc -Wall -mabi=ilp32 test-size_t.c -specs=rdimon.specs
$ aarch64-none-linux-gnu-gcc -Wall -mabi=ilp32 test-size_t.c -c
$
..what am I doing differently to your test run?
Cheers
/Marcus
