           Summary: [RFE]: Missing altmacro support in integrated
                    assembler
           Product: libraries

Hi,

While compiling coreboot, AMD's AGESA vendor assembler code blows up with the
following macro expansion:

src/vendorcode/amd/agesa/f14/gcccar.inc:38:1: error: unknown directive
.altmacro
^
<instantiation>:4:5: error: invalid instruction mnemonic 'local'
LOCAL SetupStack
~~~~^~~~~~~~~~~~~~~~
./src/cpu/amd/agesa/cache_as_ram.inc:67:3: note: while in macro instantiation
AMD_ENABLE_STACK
^
<instantiation>:5:5: error: invalid instruction mnemonic 'local'
LOCAL Real16bMode
~~~~^~~~~~~~~~~~~~~~~

This apears to be due to missing Altmacro support in LLVM's Assembler,

Cheers,
Edward O'Callaghan.
