            Bug ID: 108853
           Summary: Add new -mcpu=3De500 alias for -mcpu=3D8540
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: pali at kernel dot org
  Target Milestone: ---
            Target: powerpc*

To compile code for powerpc e500 core it is needed to specify -mcpu=3D8540
option. Name 8540 refers to the SoC MPC8540, which was the first released HW
product with powerpc e500 core. All other powerpc gcc's -mcpu options speci=
fy
core names and not the SoC/product name.

So for consistent naming I would propose to add a new option -mcpu=3De500 a=
s an
alias to -mcpu=3D8540. Note that other projects like binutils/as and LLVM u=
se
"e500" name for specifying e500 core, and not 8540 word like gcc.=
