Status: RESOLVED WORKSFORME

(SeaMonkey :: Build Config, defect)

this is probably something we want to save for the future, when gcc 3.4 is more
stable and we're ready to deal with the ABI incompatibility, but i thought i'd
file this to keep track of things.

with gcc 3.4.0, i'm seeing a 442k saving in codesize compared to 3.3.4 (both
using -Os), on linux. pretty much all of this is in layout, with the other
libraries gaining some and losing some. (the total codesize of
dist/bin/components is 12.59M, so we're talking 3.5% here.)

see also bug 225433, about moving to -Os in nightlies/releases.

Much of the -Os savings comes from gcc not aligning various bits of code. 
That's not a problem on my P4 but have you tested on other cpu's?

stale bug.
