GALLIVM_PERF_NO_OPT is "belond" to GALLIVM_PERF environment variable, not GALLIVM_DEBUG. when GALLIVM_PERF=nopt is passed to llvmpipe, "-sroa -early-cse -simplifycfg -reassociate -constprop -instcombine -gvn" should not be printed. Those llvm optimation techniques should only be printed when the default(-O2) optimation is enabled. $ GALLIVM_PERF=nopt GALLIVM_DEBUG=dumpbc glmark2 Before apply this patch: Invoke as "opt -sroa -early-cse -simplifycfg -reassociate -mem2reg -constprop -instcombine -gvn ir_setup_variant_0.bc | llc -O2 [-mcpu=<-mcpu option>] [-mattr=<-mattr option(s)>]" After apply this patch: Invoke as "opt -mem2reg ir_fs304_variant0.bc | llc -O0 [-mcpu=<-mcpu option>] [-mattr=<-mattr option(s)>]" Reviewed-by: Adam Jackson <ajax@redhat.com> Reviewed-by: Roland Scheidegger <sroland@vmware.com> Signed-off-by: suijingfeng <suijingfeng@loongson.cn> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11994>
