5374798ef9 Fix order of operations for implicit casts 2020-02-23 23:18:31 +09:00

05f6ddbb13 Print promoted warnings as errors
This makes it much easier to see why a compilation failed when only
warnings are visible.

607fd2e30e Allow constant initialized globals in advanced code
Use -C const-initializers to enable (or no-const-initializers to disable
in traditional/extended code).

e23aa40994 Implicitly cast unadorned floating point constants
Floating point constants without f or d adornments will automatically
cast, without warnings, to the type appropriate to the rest of the
expression.

4b7ecdf74a Make PR_Init take an instance to initialize
This allows internal sub-systems to do per-instance initializations
without other engine systems having to know about them.

81293d98dd Fix qfo line info dumping
The addition of xdef data has made qfo_to_progs unusable in qfprogs,
resulting in various invalid memory accesses. It always was an ugly hack
anyway, so this is the first step to proper qfo support in qfprogs.

6c6433dea5 Fetch the def name only once when scanning
Not that speed is critical at this point, but it feels better.

3aabfa71d9 Find lost type encoding relocations
I have no idea why I thought it was a good idea to delete those lines.
Yay for regression tests, though.

806af85447 Remove reference to ddef_t from progs.h
This cleans up some horrible names and redundant fields that were a
result of the transition to pr_def_t

81083698a8 Move to using an in-memory form of ddef_t
This allows the VM to work with extended ddefs transparently. It seems
to have uncovered a typedef alias relocation bug, though.

4df926e531 Write extended ddef information to progs far data
I was originally going to put it in the debug syms file, but I realized
that the data persistence code would need access to both def type and
certainly correct def offsets for defs in far data.

caf78b5422 Rename ty_none to ty_basic
This far better reflects the actual meaning. It is very likely that
ty_none is a holdover from long before there was full type encoding and
it meant that the union in qfcc's type_t had no data. This is still
true for basic types, but only if not a function, field or pointer type.
If the type was function, field or pointer, it was not true, so it was
misnamed pretty much from the start.

a6003ed08a Walk qfo alias chain for type size and alignment
While the basic type is stored in the alias type record, it's no good
for size or alignment as it will give incorrect results for complex
types.

6a70d2e362 Give alias types a unique encoding
The encoding is used as the def name and it needs to be different than
the alias target or the linker throws it away as an external def.

7a315b4a89 Fix storage class for for-loop declarations
Getting "i redeclared" when i was declared in a for loop in two
different functions was a tad unexpected.

4c40928112 Remove what appears to be a redundant check
It was long wrong anyway as it checked past the end of the function's
parameters, which caused a segfault when calling varargs functions with
no formal parameters.

c61d0b6ff0 Allow unlimited parameters in function declarations
However, definitions are still limited to 8 parameters. This allows
processing of C headers for type information.

7a399c956b Encode function parameter alignment
The encoding is 3:5 giving 3 bits for alignment (log2) and 5 bits for
size, with alignment in the 3 most significant bits. This keeps the
format backwards compatible as until doubles were added, all types were
aligned to 1 word which gets encoded as 0, and the size is unaffected.

14acfad7c4 Fix incorrect placement of far data
All the care in aligning things was undone by not updating the
calculations of the pointers.

1985b6d4fd Avoid creating a struct temp for ivar struct return
This fixed the uninitialized temp warning in HUD.r. The problem was
caused by the flow analyzer not being able to detect that the struct
temp was being initialized by the move statement due to the address of
the temp being in a pointer temp. While it would be good to use a
constant pointer for the address of the struct temp or improving the
flow analyzer to track actual data, avoiding the temp in the first place
results in nicer code as it removes a move statement.
