Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.
o add OP_JUMPB
o OP_JUMPB renumberd some opcodes, so up PROG_VERSION
pr_edict.c:
o make the version error reporting more informative
pr_exec.c:
o implement OP_JUMPB (goto *(ptr + index))
pr_opcode.c: (libs/gamecode/engine)
o add OP_JUMPB to the table
expr.h:
o ex_uinteger support
o some const correctness
o prototype new_label_expr
qfcc.h:
o uinteger ussport
o add pointers for op_jump and op_jumpb
o prototype PR_GetArray
emit.c:
o general uinteger support
o new reference/reloc type 3: absolute statement address
o jumpb support (binary goto)
expr.c:
o uinteger support
o break the label name creation out of new_label_expr into
new_label_name
o some const correctness
pr_def.c:
o add PR_GetArray to allocate an array in global space
o factor out some code common to PR_GetDef and PR_GetArray that would
otherwise be duplicated
pr_imm.c:
o some const correctness
o uinteger support
pr_lex.c:
o uinteger support
pr_opcode.c: (tools/qfcc/source)
o support jump and jumpb
switch.c:
o rewrite the binary search code to support ranges.
o add ev_uniteger to the types enum
o add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
progs.h:
o add uinteger accessors
pr_exec.c:
o implement ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
pr_opcode.c:
o add opcodes for ifbe, ifb, ifae, ifa, jump, lt.ui, gt.ui, le.ui, ge.ui
expr.h:
o prototype inc_users
qfcc.h:
o add externs for op_ifbe, op_ifb, op_ifae and op_ifa
emit.c:
o don't bother emiting an assignment to a temp def that's only used once
(ie, it's never read, only written to)
o support the new if* instructions
expr.c:
o support the new if* insructions
o dectect expression loops in append_expr
o support unsigned integers
o re-work temp def usage counting
pr_def.c
o debugging for temp def usage counts
pr_opcode.c:
o support the new if* instructions
qc-parse.y:
o provide defines for IFBE IFB IFAE IFA
switch.c:
o do binary searches for strings, floats and ints if there are more than
8 cases in a switch. Strings need more testing.
get_type and extract_type prototypes and add extern for type_names
emit.c:
use extract_type instead of get_type
expr.c:
get_type now returns the type pointer rather than the qc type enum.
extract_type uses get_type to return the qc type enum.
make type_names global
use get_type instead of ex_expr/ex_def to cover more cases
clean up function call/return processing as a result of get_type
pr_opcode.c:
use opcode_priority_type_table_ab when var_c is null and a minor
cleanup in PR_Opcode_Find
*/CRITICAL/* implication: DO NOT /EVER/ RELY ON EVALUATION ORDER. This
isn't /really/ that bad: evaluation order will be consistent for similar
expressions, but for (eg) foo() + bar()*2, bar will be called first.
integer constants and float function args/return values.
pr_comp.h:
o add the integer opcodes to pr_opcode_e
pr_edict.c:
o add "quaternion" and "integer" to type_name[]
o support quatnernion and integers types when printing values
o support the integer opcodes when bounds checking
pr_exec.c
o enable the integer opcodes
pr_opcode:
o add the integer opcodes to the opcode table
o logical operators all result in an integer rather than a value
expr.h:
o rename int_val to integer_val
qfcc.h:
o kill another magic number
expr.c:
o move the opcode to string conversion out of type_mismatch and into
get_op_string
o rename int_val to integer_val
o general integer type support.
o generate an internal comipiler error for null opcodes rather than
segging.
pr_imm.c:
o rename int_val to integer_val
o support integer constants, converting to float when needed.
pr_lex.c:
o magic number death and support quaternions and integers in type_size[]
qc-lex.l
o rename int_val to integer_val
o support quaternion and integer type keywords
qc-parse.y:
o rename int_val to integer_val
o use binary_expr instead of new_binary_expr for local initialized
variables
builtins.c:
o rename int_val to integer_val
o fix most (all?) of the INT related FIXMEs
defs.qc:
o use integer instead of float where it makes sense
main.c:
o read_result is now integer rather than float
main.qc:
o float -> integer where appropriate
o new test for int const to float arg
nuke the ex_statement and estatement_[st] stuff
add label_expr prototype
expr.c:
ex_statement nukage
correct new_expr's decl
add label_expr to ease label creation
don't crash when printing a null expression (bare return)
qc-parse.y:
estatement_t nukage
statement statements and statement_block are type expr
generate `expressions' for statements
a full parse tree for each function is now generated. there are several
special expression opcodes for statements:
d done \
r return -> unary: expression to return or null
i if binary: evaluated expression, destination label
n ifnot binary: evaluated expression, destination label
c call binary: function def, args (expr list, rev order)
s state binary: frame const, function def
g goto unary: destination label
l label unary: label number
in a top level expression, l (label) defines the label, otherwise it is a
reference.
add prototype for print_expr
expr.c:
add print_expr
correct string accessors
currect the result type for unary operators
qc-lex.l:
correct string, vector and quaternion parsing
qc-parse.y:
precedence corrections and more function scope work
CustomTF gets through the parsing again.
