            Bug ID: 95671
           Summary: Fails to build kernel 5.7 with -march=bdver{2,3,4}
                    workaround -mno-tbm
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ungift-ed at ya dot ru
  Target Milestone: ---

There is patch for build kernel with different march:
https://github.com/graysky2/kernel_gcc_patch/blob/master/enable_additional_cpu_optimizations_for_gcc_v9.1%2B_kernel_v5.7%2B.patch

Gentoo use this patch with USE='experimental'

Since 5.7 kernel builds fails on bdver{2,3,4}.
I can build kernel when add -mno-tbm

         cflags-$(CONFIG_MBULLDOZER) += $(call cc-option,-march=bdver1)
         cflags-$(CONFIG_MPILEDRIVER) += $(call cc-option,-march=bdver2)
+        cflags-$(CONFIG_MPILEDRIVER) += $(call cc-option,-mno-tbm)
         cflags-$(CONFIG_MSTEAMROLLER) += $(call cc-option,-march=bdver3)
+        cflags-$(CONFIG_MSTEAMROLLER) += $(call cc-option,-mno-tbm)
         cflags-$(CONFIG_MEXCAVATOR) += $(call cc-option,-march=bdver4)
+        cflags-$(CONFIG_MEXCAVATOR) += $(call cc-option,-mno-tbm)

Please look if it gcc issue. Thanks.
