Karoly Balogh	c577ac5ce9	m68k: add tables to convert from some stub opcodes + condition into real opcodes. Use them in the external assembler writer for now. Later the internal assembler will need these tables too.	2023-01-30 09:56:41 +01:00

Karoly Balogh	ed520548be	m68k: utilize cg.a_loadaddr_ref_cgpara in hlcgcpu, as m68k has an instruction for loading addresses directly to the stack (PEA), and the default implementation of hlcg.a_loadaddr_ref_cgpara doesn't use that code path	2022-03-23 11:06:18 +01:00
Karoly Balogh	22eb1e099f	* m68k: make sure right is in an address register for muln,addn,orn,xorn, before calling the low level cg	2022-03-22 09:02:31 +01:00

Karoly Balogh	0600287c63	* m68k: spilling read, write, and replace is now bound to CPU capabilities instead of CPU family.

Karoly Balogh	077a3f1892	* m68k: don't attempt to copy less than 1 byte in g_concatcopy, this fixes tdfa7.pp on 68000 and removes some superfluous address processing on 68020+ in the same test	2022-02-08 03:04:28 +01:00
Karoly Balogh	8f083f6342	* m68k: do not generate unnecessary unaligned load sequences for byte loads into registers, this fixes tcnvint1 test on plain 68000	2022-02-08 01:26:28 +01:00

Károly Balogh	ada3d2050c	m68k: write inline floating point immediates as hex consts, instead of scientific notation. the scientific notation format parsing depends on the libc the assembler was linked against, which can lead to varying results and compile errors ... git-svn-id: trunk@48524 -	2021-02-08 05:01:45 +00:00
Károly Balogh	d0178f7ae0	m68k: fix a_loadfpu_ref_reg to call a_loadfpu_reg_reg instead of a_load_reg_reg. made a_loadfpu_reg_reg internalerror on invalid target sizes when loading to a different reg size ... git-svn-id: trunk@48523 -	2021-02-08 04:12:21 +00:00
