Do you have a testcase? An .ll file with no 64-bit operations, and
one optimization pass that introduces

[LLVMdev] 32bit math being promoted to 64 bit
What optimization pass promotes 32 bit math operations to 64 bit
operations so I can disable it? I have code that works fine with
optimizations turned off but fails with it turned on because of this
stage.

[LLVMdev] 32bit math being promoted to 64 bit
instcombine doesn't seem to be doing it. From my testing it seems to
only occur when I use -indvars after a long string of commands.
For example:
llvm-as < test_fc_27.ll | opt -preverify -domtree -verify
-lowersetjmp -raiseallocs -simplifycfg -domtree -domfrontier
-mem2reg -globalopt -globaldce -ipconstprop -deadargelim
-instcombine -simplifycfg -ba

-instcombine -jump-threading -simpli...
