[PATCH] rs6000: suboptimal code for returning bool value on target ppc

Hello All: This patch eliminates unnecessary zero extension instruction from power generated assembly. Bootstrapped and regtested on powerpc64-linux-gnu. Thanks & Regards Ajit rs6000: suboptimal code for returning bool value on target ppc. New pass to eliminate unnecessary

[PATCH] rs6000: Inline lrint and lrintf

Hello All: Here is the patch for Inline lrint and lrintf. Currently glibc don't use __builtin_lrint as they inline lrint with fctid/fctiw instruction. With the below changes such inlines are not required and lrint builtin can be used. Bootstrapped and regtested on powerpc64-linux-gnu.

[PATCH v2] rs6000: fmr gets used instead of faster xxlor [PR93571]

Hello All: Here is the patch that uses xxlor instead of fmr where possible. Performance results shows that fmr is better in power9 and power10 architectures whereas xxlor is better in power7 and power 8 architectures. fmr is the only option before p7. Bootstrapped and regtested on

Re: [PATCH] rs6000: fmr gets used instead of faster xxlor [PR93571]

Hello All: This patch replaces fmr instruction 6 cycles with 2 cycles xxlor instruction for p7 and p8 architecture. I have implemented with switch and cases otherwise it is difficult to accommodate xxlor with p7 and p8 and fmr for other architectures. Bootstrapped and regtested. Thanks &
