f358364ef2 Fix assignment of nil to a structure.
constfold.c seems to be getting a little long in the tooth :P

28ce35f1c1 Make values independent objects.
values are now uniquely allocated (for the current object file). With
this, constants in dags will work.

f18a4d3c4a Support pointer - pointer. 2012-11-15 13:38:57 +09:00

9095e1eabc Rework build_switch to use initialize_def.
This required support for label reference expressions, whose purpose is to
represent the address of a label.

48fe9f729d Add partial support for pointer arithmetic.
Only pointer +/- integral is supported. pointer - pointer will come later.

a0788c6cdf Implement constant folding for unary operators.
Including conversions between float and int :)

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

55cc0f9206 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.

c53001800a Create a struct for representing specifiers.
The specifiers are yet to come (next few commits), but this will be
necessary when they do.

d618e51dc8 Move save_string and make_string into strpool
Might not be the perfect place, but at least they're strongly related.

d5f669af7a Nuke temp reference counting.
The whole reason for this crazy developement branch :)

52b561f7cb Nuke bind expressions.
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).

f8cc347dce Print expressions as dot files.
While the resulting images can be a little confusing, they're much easier
to read than my cryptic postfix notation.

c73ac30e3f Turns out decrementing the users was very very bad. 2011-01-11 10:56:36 +09:00

4af5dad424 More math identities.
I forgot about 0 for multiplication and division. Detects division by zero.

5b43fc1de3 Improve interaction between temps and const_folding.
Unfortunately, this seems to overdo the decrementing, so it could be
dangerous, but the ruamoko directory builds properly.

5f70e27613 Quaternions use quaternion_val, not vector_val :P 2011-01-10 13:23:12 +09:00

75ec6bf244 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.

2c84ae4898 Don't let casting in constfold increment users.
This fixes Deek's temp notice. No new notices have shown up, so this should
be the correct fix. The constant folding code no longer calls cast_expr
directly, but rather uses an internal wrapper that decrements users after
cast_expr increments it, resulting in a no-op.

40fefff847 fix incorrect users for temps resulting from casting the result of ?:
There are probably other situations, but I'll fix them as they show up.

0bd92e439a fix an interal error caused by losing the error state 2006-12-16 11:45:47 +00:00

3fb03fc2be hah, should have been using __attribute__((used)) all that time (rather
than __attribute__((unused))). fixes the missing console in -x11

634dcbba95 forgot to allow struct move (for struct assigment)
This is an imperfect revision of history.

a97f74a6ac that particular error case is a type mismatch rather than an internal error. found when trying to compare a SEL with a string... oops :)
This is an imperfect revision of history.

892e80938b that made a royal mess :( 2004-02-04 04:49:46 +00:00

b2474a2b97 better auto-conversion of function parameters (ugh, this is getting messy
:( )
2004-02-04 04:33:08 +00:00

e8a9060219 oops, messed up things like float = int 2004-02-04 00:30:42 +00:00

51b0a66ac7 better constant folding with auto-conversion between scalar types (might
make that optional for non-constants)
