Bill Currie 441e7b99bc [qfcc] Correctly implement pointer arithmetic 2020-03-17 13:39:22 +09:00
Bill Currie c5400c4581 [qfcc] Make anonstruct test robust against pointer math
I noticed that pointer math is currently incorrect in qfcc, but it would
be nice for fixing it to not break anonstruct since it is testing
something else.

Bill Currie 0d784d9ef4 [qfcc] Rework address expr calculation
This removes a bogus lea from the instruction stream (and there can be
many such).

Bill Currie 0d751dcdc5 [qfcc] Improve robustness of do_op_integer 2020-03-17 12:12:06 +09:00
Bill Currie 9cb3ee01d6 [qfcc] Add pointer value check
Extraction is a little more complicated, though, so undecided on that.

Bill Currie c3f04384d5 [qfcc] Make a general integral value extractor
All too often I just want the value.

Bill Currie 80967e1471 [qfcc] Support def exprs in integral value extractors 2020-03-17 10:56:45 +09:00

Bill Currie 888192a9ea [qfcc] Resurrect ex_def expression type
It turns out to be useful still as using symbol expressions isn't always
appropriate and the workarounds were getting nasty.

Bill Currie fd06cd2b00 [qfcc] Analyze assignment through const pointers
This fixes a false-positive uninitialized warning.
2020-03-17 01:40:35 +09:00
Bill Currie 8e6baf1bde [qfcc] Fix assigning to entity fields
At least for basic types. Compound types need testing.

Bill Currie f9face0cef [qfcc] Make is_indirect easier to read 2020-03-16 23:26:39 +09:00

Bill Currie ede7dd6d7e [qfcc] Catch attempts to emit a bad operand type 2020-03-16 20:31:21 +09:00
Bill Currie 1d10136f2e [qfcc] Treat all dereferences and indirect
Why I had a const pointer test on there is beyond me.
2020-03-16 20:24:22 +09:00
Bill Currie 69924fe717 [qfcc] Return correct value for is_const_ptr
It really helps if the logic is not inverted.
2020-03-16 20:21:07 +09:00
Bill Currie db06300ddd [qfcc] Make print_operand usable from gdb
It not emitting a \n made life difficult, especially whenever gdb
decided to make access to printf or puts awkward.

Bill Currie b544a052bf [gamecode] Bail if PR_SearchDefs is given 0 defs
Fixes the hang when searching for a field in progs that don't have any.
2020-03-16 14:24:48 +09:00
Bill Currie c8e45c6cfc [qfcc] Use operand_address in expr_deref
This fixes the technically correct but horrible mess of temps and
addressing when dealing with ivars, and the resulting uninitialized
temps due to the non-constant pointers (do need statement level constant
folding, though).
2020-03-16 14:24:48 +09:00
Bill Currie b58deb5680 [qfcc] Rewrite operand_address to be much simpler
It now creates a pointer value and returns that rather than generating
an address statement.
2020-03-16 14:24:47 +09:00
Bill Currie a0c28a5ac5 [qfcc] Support pointers to temp operands
This is necessary for correctly taking the address of operands.

Bill Currie 2f07d9a310 [qfcc] Improve accuracy of some more diagnostics 2020-03-16 10:42:18 +09:00
Bill Currie 0fe3fda44d [qfcc] Fix protocol adorned id as message receiver
This took a bit as type_id has no class data, only protocols attached to
the type_obj_object instance, and then protocol lists can get deep.
2020-03-16 10:42:18 +09:00
Bill Currie ea042cf87a [qfcc] Split out the obj-qc specific expr code 2020-03-16 10:34:16 +09:00
Bill Currie fb33a7f2a7 [qfcc] Remove "impossible" code
It is not possible to adorn Class with protocols, so no need to check
for them when checking if a type is a class.

Bill Currie e1140d476a [qfcc] Handle syntax errors in method protos 2020-03-15 16:19:45 +09:00
Bill Currie e3a1413ad3 [gamecode] Tweak output for lea 2020-03-15 10:06:37 +09:00
Bill Currie 99f89840f9 [gamecode] Show containing def and relative offset
No more guessing when accessing structure field members. Next is ivars,
I guess.

Bill Currie 3d62a7f253 [gamecode] Use fuzzy bsearch to find defs by address
The idea is to find th def that contains the address. Had to write my
own bsearch (well... lifted from wikipedia) because libc's is exact. The
defs are assumed to be sorted (which qfcc now ensures when it writes
progs and sym files).
2020-03-15 02:48:13 +09:00
Bill Currie 968de155a1 [qfcc] Make some counts unsigned
How do you have -1 def?
2020-03-15 01:33:25 +09:00
Bill Currie 9a08a51ebd [qfcc] Ensure progs defs are sorted by address 2020-03-15 01:32:38 +09:00
Bill Currie 2f9f6d3aa9 [gamecode] Relocate aux function return types
They are written with offsets relative to the type encodings base.
2020-03-14 23:39:14 +09:00
Bill Currie 067bc264fa [qfcc] Set local def size in debug sym file
It was getting random garbage. Not good for debuggers.
2020-03-14 22:08:27 +09:00
Bill Currie 20fd5eb80c [qfcc] Show def size when dumping defs 2020-03-14 22:07:36 +09:00
Bill Currie 327d692992 [qfcc] Correct order of @zero fields
This is part of what messed up float_val in the encoding for @params.
The other part is something in the linker type encoding merge code: it
may be too aggressive. It's also what messed up the size of @params.
2020-03-14 22:06:57 +09:00
Bill Currie 9492f08536 [gamecode] Print structs as well as unions
Much better :)
2020-03-14 21:03:01 +09:00
Bill Currie fea6381574 [gamecode] Rework debug type handling a little
Type encodings are used whenever they are available. For now, if they
are not, then everything is treated as void (which prints <void>, not
very useful). Most return statements and references to .return are now
very readable (excluding structs), and only params going through "..."
are a messy union.

Bill Currie 877ad35a82 [qwaq] Rework the hierarchy again
It doesn't work right now because View unconditionally sends refresh to
its textContext, but textContext can be a draw buffer which does not
respond to refresh. Still, these changes (notably the assignment chain
in qwaq-group.r really pushed qfcc).
2020-03-14 19:45:07 +09:00
Bill Currie 72f4b8ccb5 [qfcc] Give address operands a good expression
That is, those created by operand_address. The dag code needs the
expression that is attached to the statement to have the correct
expression type in order to do the right thing with the operands and
aliasing, especially when generating temps. This fixes assignchain when
optimizing (all tests pass again).
2020-03-14 19:26:47 +09:00
Bill Currie 025dd63493 [qfcc] Bubble right-hand assignee back up chain
This fixes assignchain when not optimizing. There are problems in dags,
though, with address expressions.
2020-03-14 17:48:53 +09:00
Bill Currie 97e0c23529 [qfcc] Create a nil operand
This is for struct assignments so they can pass the source operand back
up the assignment chain.
2020-03-14 17:47:23 +09:00
Bill Currie eca976e5ae [qfcc] Expose l-value checking
Needed for assignment chains.
2020-03-14 17:45:54 +09:00
Bill Currie 7d5644e055 [qfcc] Save operand creator return address 2020-03-14 17:44:54 +09:00
Bill Currie 51a30de9c5 [qfcc] Print accurate linenos for more ICEs 2020-03-14 16:51:54 +09:00
Bill Currie 6608c8a1f6 Revert "Support taking the address of block expressions that have a result."
This reverts commit c78d15b331.

While a block expression's result may be an l-value, block expressions
are not (and their results may not be), thus taking the address of one
is not really correct. It seems the only place that tries to do so is
the assignment code when dealing with structures.
2020-03-14 13:14:25 +09:00
Bill Currie 277ff719f5 Revert "Do not lose the block expression when taking its address."
This reverts commit b49d90e769.

I suspect this was a workaround for the mess in assignment chains.
However, it caused compile errors with the new implementation, and is
just bogus anyway.
2020-03-14 12:30:18 +09:00
Bill Currie 7cc51c9ca3 [qfcc] Save block expression creator's address
I've already found the bug that necessitated it (and the creator was
innocent), but it will help later.
2020-03-14 12:27:23 +09:00
Bill Currie d30c895c13 [qfcc] Use correct assignment statement type
Just another minor detail lost in the assignment rewrite. With this, all
tests pass when optimizing.
2020-03-14 11:36:42 +09:00
Bill Currie a98f0e04eb [qfcc] Correct some misinformative prints 2020-03-14 01:28:00 +09:00
Bill Currie b1459ac816 [qfcc] Move return save temp into call block
This fixes func-expr after the assignment rewrite. Now all tests pass
when not optimizing (something not quite right in assignchain when
optimizing).
