softfloat: Name rounding mode enum

2020-05-19T15:41:26+00:00

Give the previously unnamed enum a typedef name. Use the packed attribute so that we do not affect the layout of the float_status struct. Use it in the prototypes of relevant functions. Adjust switch statements as necessary to avoid compiler warnings. Reviewed-by: Alex Bennée Reviewed-by: Philippe Mathieu-Daudé Signed-off-by: Richard Henderson

target/m68k/fpu_helper.c: rename the access arguments

2019-09-19T10:12:19+00:00

The "access" arguments clash with a macro under Windows with MinGW: CC m68k-softmmu/target/m68k/fpu_helper.o target/m68k/fpu_helper.c: In function 'fmovem_predec': target/m68k/fpu_helper.c:405:56: error: macro "access" passed 4 arguments, but takes just 2 size = access(env, addr, &env->fregs[i], ra); So this renames them access_fn.

target/m68k: Fix LGPL information in the file headers

2019-01-30T13:20:13+00:00

It's either "GNU *Library* General Public License version 2" or "GNU Lesser General Public License version *2.1*", but there was no "version 2.0" of the "Lesser" license. So assume that version 2.1 is meant here. Also some files mention the GPL instead of the LGPL after declaring that the files are licensed under the LGPL, so change these spots to use LGPL, too.
