[build] Fix a pile of gcc 10 issues
...
gcc got stricter about array accesses, complicating progs macros, and
much better at detecting buffer overflows.

[gamecode] Tweak types in dfunction_t
...
Mostly minor corrections to make more sense when reading them.

[gamecode] Rework implementation of memset*
...
The memset instructions now match the move* instructions other than the
first operand (always int). Probably breaks much, but fixed in next few
commits.

[gamecode] Add memset instructions

Add a breakpoint flag to opcodes
...
The progs execution code will call a breakpoint handler just before
executing an instruction with the flag set. This means there's no need
for the breakpoint handler to mess with execution state or even the
instruction in order to continue past the breakpoint.
The flag being set in a progs file is invalid.

Make pr_obcode.c mostly thread safe
...
Its public data is all read-only, and once set up, its private data is
too (just don't call init in multiple threads).

Make a bunch of count things positive-only
...
This fixes a pile of FIXMEs, because some things should never be
negative.

Make header protection consistent

Do lazy computation of def sizes from type encodings

The size is calculated when needed and cached.

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.

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.
2020-02-22 22:33:44 +09:00
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.

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.

Implement true modulo in the engine
2020-02-16 11:53:56 +09:00

Rename the mod instruction to rem
...
Because % really implements remainder rather than true modulo, and I
plan on adding %% to implement true modulo.

Add support for doubles to Ruamoko
...
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.

Add a stack and push and pop instructions.

Attempt to autoconfiscate gcc_struct.

It seems some tool-chains get rather picky about such things.

Use __attribute__((gcc_struct)) on dstatement_t.
...
Trust Microsoft to have really weird structure layout rules. Ah, well, this
fixes the weird progs errors Sock was getting.

Change pointer_t to unsigned and clean up the mess.
...
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

Bring back the unsigned type (PROGS version bump)
...
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

Clean out some unnecessary types from the progs engine and clean up the mess.

This is a nasty commit, sorry, but 99% of the commit is interdependent.

do proper selector registration. unfortunatly, I discovered I'd created pr_method_t incorrectly and so had to bump the progs version again
