222bcb808f optimize load-store-load combo in output asm 2021-11-10 23:47:35 +01:00
Irmen de Jong
8df3da11e3 add cosr8, sinr8, cosr16 and sinr16 builtin functions that take a degree 0..179 (= 0..358 in 2 degree steps) 
to more easily scale halves/quarters etc of a circle than possible with the ones that take 0..255 'degrees'.

eea3fb48a8 add command line option 'optfloatx' to explicitly re-enable float expr optimization as this can increase code size significantly. 
The output size of the various example programs using floating point, when not using this optimization, has been reduced significantly.
The resulting code runs a (tiny) bit slower though.

928611eb20 Got rid of problematic attempts to save status register after function calls. If you really need it (for instance for if_XX instructions) it's probably better to use a short asmsub wrapper. 
For function calls, register saves go via stack (to allow nested saves) for simpler cases, registers are saved in a local variable.
Fixed too agressive removal of sta-lda sequence if the lda is followed by a branching instruction.
Insert missing cmp #0 after functioncall if the value of the A register is needed in a comparison expression (could otherwise test wrong status flag)
