[Qemu-devel] [PATCH] target-mips: Remove semicolon from macro definition

[Qemu-devel] [PATCH] target-mips: Remove semicolon from macro definition

[Stefan Weil]

Macro RESTORE_FLUSH_MODE is similar to RESTORE_ROUNDING_MODE
but included a semicolon.

The code which uses that macro also includes a semicolon,
so the result was an empty statement.

Remove the superfluous semicolon from the macro definition.

Note:

After the patch, the modified line is shorter, but still longer than
required by the coding conventions.

FWIW I think it would be better to just turn these two macros into
static inline functions which took a CPUMIPSState *env argument.
Macros which don't take arguments but silently use variables from
their caller are a bit ugly, and in this case there's no need to do it
that way.

Thanks, applied.
