- Subject: ENUM_BITFIELD and -fshort-enums
I tried to build a native arm-unknown-linux-gnueabi compiler yesterday.
The only major problem was the fact that EABI defaults to
-fshort-enums. rtl.h has this:
/* The kind of expression this is. */
ENUM_BITFIELD(rtx_code) code: 16;
But since there are only 164 RTL codes at present, with -fshort-enums
the underlying type of enum rtx_code is "char". So GCC gives an error
that the bitfield is wider than its type.
For now I'm just using an x-linuxeabi file which builds GCC using
-fno-short-enums, but that's not a good solution. Should this bitfield
be allowed?
