Hi,
Attached is a patch to fix(?) PR/13721.
If one uses a machinde-dependent operand character in a way
inconsistent with the corresponding constraint in an inline asm
statement, h8300-elf-gcc may segfault.
The patch changes that to ICE, which says where the error occurs at
least.
Built h8300-elf. Committed to both mainline and 3.4 branch.
