0730e86c9d m68k: refactor - use the new CPUM68K_HAS_TSTAREG capability where applicable 2025-02-17 12:03:24 +01:00
Karoly Balogh
e09304f671 m68k: do not try to optimize CMP #0,Ax to TST Ax, if the CPU doesn't support it 2025-02-17 12:03:24 +01:00

e507f612f5 m68k-palmos: further fixes to assembly section. also actually use aout, as we have aout binutils for palmos 2024-05-25 00:14:11 +03:00
Karoly Balogh
627734e104 m68k: try to fold two consecutive AND instructions into one. This usually happens when a zero extension is followed by another AND. 2024-05-25 00:01:35 +03:00

88ffc9e228 m68k: refactored the optimizer to avoid direct asml management where possible, and use standard functions instead 2024-01-09 03:03:27 +01:00
Karoly Balogh
020ca55e25 m68k: add more cases, where TST instructions can beoptimized away, because the previous instruction already sets all the required flags 2024-01-08 15:06:38 +01:00

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

59c33d69ab Revert "m68k: utilize cg.a_loadaddr_ref_cgpara in hlcgcpu" for now, turns out it's not needed 2022-03-24 09:48:25 +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
be2c1c751d * m68k: fixed the register save/restore for larger than 32K stackframes on subarchs which has no long displacement, to not trash register A0 2022-03-12 21:22:42 +01:00
Karoly Balogh
0600287c63 * m68k: spilling read, write, and replace is now bound to CPU capabilities instead of CPU family. This probably fixes some issues on 68000, where spilling replacement was not respecting CPU displacement handling boundaries, leading to assembler errors. 2022-03-11 16:03:21 +01:00

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
Karoly Balogh
