RE: [PATCH] Fix for PR 14423 - Assembler doesn't recognize fma instructions in bdver2 core
The files (arch-10.s and x86-64-arch-2.s) already does fma testing but it doesn't test whether a specific core (bdver2) supports fma or not.
Re-using these assembly files and creating new .d(objdump) files with -march=bdver2 will not help, because these files have un-supported bdver2 instructions.
So, is there a way to test a core against one/all of the supported instructions in the existing Assembler test framework?
If not, adding a new testscase for this bug is the only option I guess.

Please add the FMA test to arch-10.s and x86-64-arch-2.s instead.
