cproc: Implement defer statement.

2024-11-06T11:17:01+00:00

implemented by keeping a list of deferred blocks in a function, and emitting them before scope exits (return, lbracket, break, continue) TODO: error checking, the compiler should error should a compile time jump (goto) would go over a defer statement.

Store enum constant value in struct decl

Implement variable length arrays

2024-04-27T22:34:03+00:00

Variably modified types are required for C23. Since QBE doesn't currently support saving and restoring the stack pointer, a current limitation is that we can't reclaim stack space from VLAs that go out of scope. This is potentially problematic for VLAs appearing in a loop, but this case is uncommon enough that it is silently ignored for now.

qbe: Add extra size for strict alignment with QBE instruction

2024-04-27T21:29:02+00:00

With upcoming VLA support, the size might not be constant.

qbe: Temporarily set func->end = func->start in funcalloc

This way way can just use funcinst.

Use hlt to implement noreturn

expr: Collapse *& when parsing

qbe: Use expression type when loading

2024-04-27T08:12:22+00:00

If we are loading the first element of an array, or first member of a structure, the expression type may be different from the object type.

decl: Move isnoreturn to struct decl

2024-04-27T01:07:36+00:00

It is a property of the declaration, not the type.
