+Description: An improved Quake C Compiler
+ For an enduring period of time the options for a decent compiler for the Quake C programming language
+ were confined to a specific compiler known as QCC. Attempts were made to extend and improve upon the
+ design of QCC, but many foreseen the consequences of building on a broken foundation. The solution
+ was obvious, a new compiler; one born from the NIH realm of sarcastic wit. We welcome you. You won't
+ find a better Quake C compiler.

Warn when the initialization of a local variable turns the variable
into a constant. This is default behaviour unless

expected to have an implementing body, or be a builtin. If neither is
the case, it implicitly becomes a function pointer, and a warning is
generated.

Warn when assigning to a function pointer with an unmatching
signature. This usually happens in cases like assigning the null
function to an entity's .think function pointer.

Enable warnings coming from the preprocessor. Like duplicate macro
declarations. This warning triggers when there's a problem with the
way the preprocessor has been used, it will \fBnot\fR affect warnings
generated with the '#warning' directive. See -Wcpp.

in QC code so you probably do not want this unless you want to clean
up your code.

The combination of \fIconst\fR and \fIvar\fR is not illegal, however
different compilers may handle them differently. We were told, the

This is exactly how we interpret it. However for this interpretation

without enclosing parenthesis, since this is most likely not what you

token inside the enclosing attribute-brackets. This may change when
the actual attribute syntax is better defined.

-.B -Wuninitialized-global

default, and is added mostly to help find null-values which are
supposed to be replaced by the untyped 'nil' constant.
-.TP
-.B -Wdifferent-qualifiers
+.It Fl W Ns Cm different-qualifiers
Warn when a variables is redeclared with a different qualifier. For
example when redeclaring a variable as \'var\' which was previously
marked \'const\'.

Warn when a function is marked with the attribute
"[[deprecated]]". This flag enables a warning on calls to functions
marked as such.
-.TP
-.B -Wparenthesis

Warn about possible mistakes caused by missing or wrong parenthesis,
like an assignment in an 'if' condition when there's no additional set
of parens around the assignment.

-.TP
-.B -fadjust-vector-fields
+.It Fl f Ns Cm adjust-vector-fields
When assigning to field pointers of type \fI.vector\fR the common
behaviour in compilers like \fIfteqcc\fR is to only assign the
x-component of the pointer. This means that you can use the vector as
such, but you cannot use its y and z components directly. This flag
fixes this behaviour. Before using it make sure your code does not
depend on the buggy behaviour.

Perform early out in logical AND and OR expressions. The final result
will be either a 0 or a 1, see the next flag for more possibilities.
-.TP
-.B -fperl-logic
+.It Fl f Ns Cm perl-logic
In many languages, logical expressions perform early out in a special
way: If the left operand of an AND yeilds true, or the one of an OR
yields false, the complete expression evaluates to the right side.
-Thus \fItrue && 5\fI evaluates to 5 rather than 1.

+Thus

+Enable the underscore intrinsic: Using

will cause the string immediate to get a name with a "dotranslate_"
prefix. The darkplaces engine recognizes these and translates them in
a way similar to how gettext works.
-.TP
-.B -finitialized-nonconstants

Don't implicitly convert initialized variables to constants. With this

-.TP
-.B -fassign-function-types

If this flag is not set, (and it is set by default in the qcc and
fteqcc standards), assigning function pointers of mismatching

An empty string is considered to be true everywhere. The NOT_S

effectively causes the unary not in strings to use NOT_F instead.

An empty string is considered to be false everywhere. This means loops

Most Quake VMs, including the one from FTEQW or up till recently

+.Bl -tag -width Ds
+.It Fl O Ns Cm peephole
Some general peephole optimizations. For instance the code `a = b + c`
typically generates 2 instructions, an ADD and a STORE. This
optimization removes the STORE and lets the ADD write directly into A.
-.TP
-.B -Otail-recursion
+.It Fl O Ns Cm tail-recursion
Tail recursive function calls will be turned into loops to avoid the
overhead of the CALL and RETURN instructions.
-.TP
-.B -Ooverlap-locals
+.It Fl O Ns Cm overlap-locals
Make all functions which use neither local arrays nor have locals
which are seen as possibly uninitialized use the same local section.
This should be pretty safe compared to other compilers which do not
it's hard to know whether or not an array is actually fully
initialized, especially when initializing it via a loop, we assume
functions with arrays to be too dangerous for this optimization.
-.TP
-.B -Olocal-temps
+.It Fl O Ns Cm local-temps
This promotes locally declared variables to "temps". Meaning when a
temporary result of an operation has to be stored somewhere, a local
variable which is not 'alive' at that point can be used to keep the
result. This can reduce the size of the global section.
This will not have declared variables overlap, even if it was
possible.
-.TP
-.B -Oglobal-temps
+.It Fl O Ns Cm global-temps
Causes temporary values which do not need to be backed up on a CALL to
not be stored in the function's locals-area. With this, a CALL to a
function may need to back up fewer values and thus execute faster.
-.TP
-.B -Ostrip-constant-names
+.It Fl O Ns Cm strip-constant-names
Don't generate defs for immediate values or even declared constants.
Meaning variables which are implicitly constant or qualified as such
using the 'const' keyword.
-.TP
-.B -Ooverlap-strings
+.It Fl O Ns Cm overlap-strings
Aggressively reuse strings in the string section. When a string should
be added which is the trailing substring of an already existing
string, the existing string's tail will be returned instead of the new
string being added.
-
+.Pp
For example the following code will only generate 1 string:
-
-.in +4
-.nf
+.Bd -literal -offset indent
print("Hell you!\\n");
print("you!\\n"); // trailing substring of "Hello you!\\n"
-.fi
-.in
+.Ed
+.Pp
There's however one limitation. Strings are still processed in order,
so if the above print statements were reversed, this optimization
would not happen.
-.TP
-.B -Ocall-stores
+.It Fl O Ns Cm call-stores
By default, all parameters of a CALL are copied into the
parameter-globals right before the CALL instructions. This is the
easiest and safest way to translate calls, but also adds a lot of
optimization makes operations which are used as a parameter evaluate
directly into the parameter-global if that is possible, which is when
there's no other CALL instruction in between.
-.TP
-.B -Ovoid-return
+.It Fl O Ns Cm void-return
Usually an empty RETURN instruction is added to the end of a void
typed function. However, additionally after every function a DONE
instruction is added for several reasons. (For example the qcvm's
disassemble switch uses it to know when the function ends.). This
optimization replaces that last RETURN with DONE rather than adding
the DONE additionally.
-.TP
-.B -Ovector-components
+.It Fl O Ns Cm vector-components
Because traditional QC code doesn't allow you to access individual
vector components of a computed vector without storing it in a local
-first, sometimes people multiply it by a constant like '0 1 0' to get,
+first, sometimes people multiply it by a constant like
+.Ql '0 1 0'
+to get,
in this case, the y component of a vector. This optimization will turn
such a multiplication into a direct component access. If the factor is
anything other than 1, a float-multiplication will be added, which is
still faster than a vector multiplication.
