5020966be3 [qfcc] Fix ud-chain alias handling 
That was a fair bit trickier than I thought, but now .return and .paramN
are handled correctly, too, especially taking call instructions into
account (they can "kill" all 9 defs).

3d9410c66d [qfcc] Force overlap to 0 for non-alias def/temops 
Make the code behave as intended: visiting all aliases when starting
with the real def/tempop regardless of the overlap setting.
 2020-03-08 16:53:28 +09:00
Bill Currie
035da472ec [qfcc] Offset alias tempop offsets 
Alias tempop offsets are relative to the real tempop. This fixes alias
tempops never overlapping the real tempop.

695b3ba0d0 [qfcc] Rearrange vecexpr.r for easier debugging 
Putting the most likely function to have problems at the top reduces
break-point shenanigans.

d9d321f65b [qfcc] Check for previous errors in vector exprs 
Fixes a segfault when one of the expressions used to construct the
vector was the result of an error.

b81d58c795 Revert "[qfcc] Correct a comment" 
This reverts commit a2f203c840.

There is indeed a world of difference between "any" and "only", and it
helps if I read the rest of the docs AND the code :P.

8696e76a25 [qfcc] Handle aliases when setting use and def 
As expected, this does not fix the mangled pointer problem in
struct-init-param.r, but it does improve the ud-chains. There's still a
problem with .return, but it's handling in flow_analyze_statement is a
bit "special" :P.

a2f203c840 [qfcc] Correct a comment

b2faca16a7 [qfcc] Rename the kill alias functions 
Having "visit" in the name felt redundant in the end.
 2020-03-08 12:08:56 +09:00
Bill Currie
c2ed6d41bd [qfcc] Finish struct-init-param test 
When the bug is fixed, it will pass now (does without optimization).

e4c87091a3 [qfcc] Lots of flow analysis docs 
And some function shuffling for grouping. I'm not satisfied with the
docs, but they're a lot more helpful than they were.

809c103fd1 [qfcc] Shuffle some code around to be clearer 
Doing the same thing at the end of two branches of an if/else seems off.

And doing an associative(?) set operation every time through a loop is
wasteful.
 2020-03-08 03:46:52 +09:00
Bill Currie
7338689146 [qfcc] Treat offset real tempops as an error 
tempops always have an offset field, but only those that are aliases
should ever have a non-zero offset.

d44d956038 [qfcc] Remove a long dead function 2020-03-08 03:39:24 +09:00

f56de00c21 [qfcc] Rename a field 
depth_first is much clearer than dfo. I had to check what dfo meant too
many times in one night.

2b15e61b28 [qfcc] Remove obsolete structure fields 
init_vars hasn't been used for a long time.

e524db1fc1 [qfcc] Set op type when aliasing a value 
This fixes the ICE when attempting to compile address-cast without
optimization (just realized why, too: the assignment was optimized out
of existence).

777ce56cf3 [doc] Enable MathJax 
Nice. Very nice.

48514ba2f3 [qfcc] Create alias def for defs accessed via pointer 
This the fixes the incorrect flow analysis caused by the def being seen
to have the wrong size (structure field of structure def seen through a
constant pointer). Fixes the ICE, but the pointer constant is broken
somewhere in dags, presumably.

faa6eabfbe [qfcc] Add a failing test for struct init to param 
This actually took a bit to reproduce.

de06efa604 [qfcc] Fix handling of nil for static initializers 
nil is most definitely constant.
 2020-03-06 20:38:40 +09:00
Bill Currie
9dbc81432a [qfcc] Use full type for differentiating values 
This fixes the problem of using nil for two different compound types
within the one expression. The problem is all compound types have the
same low-level type (ev_invalid) and this caused the two different nils
to have the same type when taken back up to expression level.

07e6baf32f [qfcc] Support { } as nil in nested initializers 
Did top-level earlier, but forgot to add support for deeper nestings.
 2020-03-06 20:32:37 +09:00

1250fe7446 [qwaq] Use a log file instead of stderr 
Now I don't have to worry about remembering to redirect the output, but
debugging is still easy.

b8b74fc074 [qwaq] Implement missing addch 
I either forgot about it, or just didn't need it at the time, but I'm
sure it will be useful later when more stuff is implemented.

9a96a9b2c9 [qwaq] Use own version of positional drawing in Window 
Double offsetting the prints doesn't quite look right ;)

bea64838cc [qwaq] Use new TextContext 
Not quite right yet, but it worked first try (once I got another
compiler bug sorted).

9b269c2f8e [qfcc] Fix mangled method parameters 
Method parameters (ie, extra parameters without selector names) were
getting reversed during function type construction.

ba9c43d2d3 [qwaq] Create a TextContext class 
It is essentially just a wrapper around the window versions of ncurses
functions.

40ae7a7f19 [qwaq] Implement ofDontDraw 
The conditional selector performance seems to work nicely, but I've
found a mistake with View.window (partly, realizing why my old lib (and
probably TV in the first place) had separate textContext and buffers
between views and groups).

6bf2fd546d [qwaq] Extend Array makeObjectsPerform methods 
Added conditional message sending and reversed traversal of the array.

3b959c3ed0 [gamecode] Add a macros for arbitrary param/return types 
Of course, the type has to be small enough to fit or bad things may
happen, but it beats having to type the crazy casting every time.

66b8ab6890 [qfcc] Rework method ivar access 
While expression symbols worked for what they are, they weren't so good
for ivar access because every ivar of a class (and its super classes)
would be accessed at method scope creation, generating spurious access
errors if any were private. That is, when the access checks worked at
all.

59db90d177 [qfcc] Fix method not found warnings 
It turns out they should not be optional, but do need to be smarter
about when and which. So another two FIXMEs gone :)

ccaa4ad3d2 [qfcc] Catch assignment of void* to class pointers 
id and other class pointers imply that the object can receive messages,
but void * has no such implication, so treat it as a mismatch.
