Subject: [PATCH] sandbox: make function 'do_undefined' properly compiles for PowerPC
Date: Tue, 30 Apr 2024 16:34:42 +0800 [thread overview]
Message-ID: <80535f3983d4df93bfbeaed881e60096.squirrel@_> (raw)
[-- Attachment #1: Type: text/plain, Size: 417 bytes --]
The 2 bytes 0xffff is too short for being a PowerPC instruction, resulting
in an error similar to:
/tmp/ccW8yjie.s: Assembler messages:
/tmp/ccW8yjie.s: Error: unaligned opcodes detected in executable segment
/tmp/ccW8yjie.s:223: Error: instruction address is not a multiple of 4
make[2]: *** [/tmp/ccyF4HIC.mk:17: /tmp/ccCKUFuF.ltrans5.ltrans.o]
Error 1
