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.

9851d14fb9 added if expression: ubyte a = if b>0 44 else 55
it doesn't generate the best code yet, like regular ifs do.

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.

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

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

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.

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)

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.
