Irmen de Jong	7585b6ef6f	fix issues with calling the defer handler	2024-10-21 19:49:38 +02:00
Irmen de Jong	a6159702da	defers are now only registered/called when flow of control actually reached the defer statement ... a defer statement sets its corresponding bit in a bitmask that is shifted in the defer handler routine to see what defer blocks to call.	2024-10-21 00:55:51 +02:00
Irmen de Jong	0247fb0d84	some ast2 var tweaks	2024-10-21 00:20:54 +02:00

Irmen de Jong	9851d14fb9	added if expression: ubyte a = if b>0 44 else 55 ... it doesn't generate the best code yet, like regular ifs do.	2024-10-19 15:34:04 +02:00
Irmen de Jong	d5fc69d3e4	fix instruction index error in optimizer	2024-10-19 14:45:53 +02:00

Irmen de Jong	fcdd9414d9	fix defer interfering with return value, fix prefix expression error when operand is functioncall that doesn't return a value.	2024-10-18 21:43:09 +02:00
Irmen de Jong	272a1001a8	fix bad optimization of floats.pop/push call	2024-10-18 21:04:18 +02:00

Irmen de Jong	d8f1822c12	fixes	2024-10-18 20:32:46 +02:00
Irmen de Jong	ce7d094adb	Zig-like "defer" to clean up stuff when leaving the scope of the current routine.	2024-10-18 01:30:20 +02:00
Irmen de Jong	a0cf1889a3	omit more redundant 0-initializations ("stz's")	2024-10-17 22:51:39 +02:00
Irmen de Jong	38ef394e15	IR codegen: global vars with numeric initialization value are now also put into the VARIABLESWITHINIT section rather than requiring explicit code instructions to initialize them in INITGLOBALS. ... Note that something similar, such as putting those variables inline in the program initialized with their value and all, cannot be done for the 6502 codegen: the program needs a mechanism to reset ALL variables when it runs a second time.	2024-10-16 22:15:51 +02:00
Irmen de Jong	abbf7c7cb0	compiler name change: prog8c (was p8compile) ... fat jar file also changed: prog8c-X.Y-all.jar (was: prog8compiler-X.Y-all.jar)	2024-10-16 18:36:19 +02:00
Irmen de Jong	ca5f7ae32f	global (block-level) variables that get initialized with an array index expression now get a constant value as well if possible. This reduces the number of instructions in the init globals code block	2024-10-16 02:14:19 +02:00
Irmen de Jong	cbc4b75e50	IR now contains "bool" as a type instead of already erasing it into "ubyte". (boolean literals still are simply just 1 and 0 values)	2024-10-16 01:03:35 +02:00
Irmen de Jong	65ddcf91d0	remove unused syscalls	2024-10-15 18:24:55 +02:00

Irmen de Jong	b6ffb81909	Merge branch 'next-version'	2024-10-13 21:20:10 +02:00
Irmen de Jong	e9edffa9f0	remove support for array-to-array assignments (other than initialization of variable declaration) ... Just use an explicit sys.memcopy(src, dest, sizeof(dest)) or assign array members individually.	2024-10-13 20:02:43 +02:00
Irmen de Jong	0dd1c17ff4	avoid possible crash	2024-10-13 17:51:14 +02:00
Irmen de Jong	aef211e5f3	stricter array literal element type handling (number,bool,address-of). ... More consistent implicit address-of handling if array literals contain by-ref identifiers (such as subroutine names)	2024-10-13 17:46:41 +02:00
Irmen de Jong	66829203d8	New [x]*42 syntax to create array literals with repeated values (like "abc"*10 already exists for strings) ... Should be used in place of array initializer expressions that contain only a single numeric value to initialize the whole array with. That isn't supported anymore.	2024-10-13 05:16:08 +02:00
Irmen de Jong	7a0eaf3148	Remove array initialization by single value. ... New compiler and kotlin version.	2024-10-13 04:31:56 +02:00
Irmen de Jong	fa5479ee5f	fix ast printing of arrays with duplicate elements	2024-10-13 04:30:46 +02:00

Irmen de Jong	5731b79554	don't allow problematic string and array assignments anymore, improve error messages. ... In certain cases you will need to use string.copy() explicitly to overwrite strings with new strings.	2024-10-09 00:51:05 +02:00

Irmen de Jong	ae669af904	add sys.sizeof_byte, _word, _float constants ... because Antlr doesn't allow the grammar to contain a sizeof(typename) rule to override the sizeof(identifier) rule	2024-10-07 19:17:37 +02:00
