2011-10-26target-sparc: Pass float64 parameters instead of dt0/1 temporaries.Richard Henderson
Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-10-26target-sparc: Add accessors for double-precision fpr access.Richard Henderson
Begin using i64 quantities to manipulate double-precision values. On a 64-bit host this will, for the moment, generate less efficient code; on a 32-bit host code quality should be largely unchanged. Code quality for 64-bit will be adjusted with a subsequent patch. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-26target-sparc: Add accessors for single-precision fpr access.Richard Henderson
Load, store, and "create destination". This version attempts to change the behaviour of the translator as little as possible. We previously used cpu_tmp32 as the temporary destination, and we continue to use that. This will eventually allow a change in representation of the fprs. Change the name of the cpu_fpr array to make certain that all instances are converted. Signed-off-by: Richard Henderson <rth@twiddle.net>

2011-10-25main-loop: Add missing include fileStefan Weil
stdint.h defines the POSIX data types and is needed for MinGW-w64 (and maybe other hosts). v2: Instead of adding stdint.h directly, qemu-common.h is now included and duplicate include statements were removed.

2011-10-25target-sparc: Fix use of g_new0 / g_freeStefan Weil
g_malloc0 needs g_free instead of free. While fixing this, I also replaced g_malloc0 by g_new0 as was suggested by Stuart Brady. Cc: Blue Swirl <blauwirbel@gmail.com> Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-10-25target-sparc: Fix order of function parametersStefan Weil
The MinGW-w64 gcc complains about wrong parameters for gen_helper_fpadd16_s and three other functions. gen_helper_fpadd16_s is declared like this (hidden in lots of macros): static inline void gen_helper_fpadd16s(TCGv_i32 retval, TCGv_ptr arg1, TCGv_i32 arg2, TCGv_i32 arg3); So it looks like cpu_env should be the 2nd parameter. Please review this patch as I have no environment to test it (maybe the 1st parameter should be cpu_dst?).

Fix the "-version" option, which was accidentally broken in commit fc9c541: * exit after printing version information rather than proceeding blithely onward (and likely printing the full usage message) * correct the cut-n-paste error in the usage message for it * don't insist on the presence of a following argument for options which don't take an argument (this was preventing 'qemu-arm -version' from working) * remove a spurious argc check from the beginning of main() which meant 'QEMU_VERSION=1 qemu-arm' didn't work.
