------- Comment #18 from jakub at gcc dot gnu dot org 2009-01-27 15:14 ------- The problem on ix86 is I believe that on such a register starved host, using long long in many places will mean very noticeable performance degradation.
In any case, I'd prefer to change tree-vrp.c at this point (am going to bootstrap/regtest it), with the testcase with -w in dg-options, and handle the rest separately, as P2. The rest is certainly not a recent regression (3.4.0 behaves the same way between i386 cc1 and x86_64 cc1 -m32). -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38934
