[Bug bootstrap/34205] enum type/size error

[pbrook at gcc dot gnu dot org]

------- Comment #13 from pbrook at gcc dot gnu dot org  2007-11-28 19:05 -------
The short answer is don't do that.

-mabi=iwmmxt selects a bare-metal (short-enum) AAPCS variant with iWMMXt
calling conventions. As such it is incompatible with the Linux EABI supplement
(http://www.codesourcery.com/gnu_toolchains/arm/arm_gnu_linux_abi.pdf) which
requires long-enums.

If you want iwmmxt calling conventions on linux you'll have to define and add a
new ABI variant.

In theory gcc should probably be fixed to support short-enum host systems.
In practice all vaguely interesting host systems use long enums, and other bits
of a linux system will explode if built with -fshort-enums, so I'm closing this
as WONTFIX.
