------- Comment #3 from gunnar at greyhound-data dot com 2008-05-29 12:50 ------- Created an attachment (id=15699) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=15699&action=view) Prefer 4 byte long LEA over 6 byte long ADD.L
Please include the attached patch for GCC. The added patch has changed the case statement to prefer the 4 byte long lea over the 6 byte long add.l for immediate sub/add instructions to address registers with an immediate operant size of 16bit max. LEA is optimized for pipelining (with destination forwarding) and is shorter than ADD.L Regards Gunnar von Boehn -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36134
