Well, it may not be earth-shattering, but it's still a solid improvement - of more than a few %! With rev. 131446 I get the following numbers: -O1 -fstrict-aliasing: 11sec, 201825 kB -O2: 22sec, 392166 kB -O3: 24sec, 388802 kB Compile time is reduced by a factor of 4 for -O2, and memory usage is halved for -O1! Nice job, Richard. So I'd say compile time really isn't an issue any more. But memory consumption is still a factor of 10 above what it was last year. Most of that comes from 'tree FRE' (~140MB), but all the junk in 'tree operand scan' is gone. For -O2 and -O3 another large chunk appears in 'tree PRE' (~160MB). Are you sure you want to close this bug? For me memory consumption is still an issue, and I would really like to see this fixed at some point. And if there is another bug which is a duplicate of this, could you point me to it? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34683
