MASM .xmm "Enables assembly of Streaming SIMD Extension instructions.", whereas gas .arch "enables a warning when gas detects an instruction that is not supported on the CPU specified". So based on the documentation, the behavior is opposite: MASM is a lower limit, gas is an upper limit. Since pentium4 cannot support any 64-bit instructions, it is rejected.

Removing the .arch directive from xhelpers.m4 allows the build to complete. There's more in runtime/makelib/masm2gas.pl and the same in OMR, but those don't seem to be used in the normal build. In principle, it could also be output in 32-bit mode only.

I encountered that and simply removed that line to build with gcc 13.2. There are other changes that I found necessary, but I haven't verified that those are safe for all versions.
