* softfloat: Name rounding mode enumRichard Henderson2020-05-191-3/+3
| | | | | | | | | | | | 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.

* target/m68k/fpu_helper.c: rename the access argumentsKONRAD Frederic2019-09-191-4/+4

| | | | | | | | | | | | | | | 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.

* target/*/cpu.h: remove softfloat.hAlex Bennée2018-02-211-0/+1
| | | | | | | | | | | | | | | | | As cpu.h is another typically widely included file which doesn't need full access to the softfloat API we can remove the includes from here as well. Where they do need types it's typically for float_status and the rounding modes so we move that to softfloat-types.h as well. As a result of not having softfloat in every cpu.h call we now need to add it to various helpers that do need the full softfloat.h definitions.
