Re: [PATCH v2 21/30] Deprecate 32 bit big-endian MIPS

[Pierre Muller]

  I am using gcc230 machine for the gcc compile farm.

  This is a big endian mips64 machine runnig Debian Buster.

When compiling the qemu 7.1.0 release source,
the generated binaries are 32-bit mips binaries,
and I did not find out how to generate a 64-bit versions
of the executables.

  As mips32 seems to still be the default arch that gcc uses,
I don't really understand the idea of depreciating big endian mips32.

Is this solely related to cross-compilation issues?
