\fBgmqcc\fR optionally takes options to specify the output and
input files on the commandline, and also accepts assembly files.
.SH OPTIONS

there are also traditional long-options available.

+DEBUG OPTION. Print the code's intermediate representation before the
+optimization and finalization passes to stdout before generating the
+binary.

+DEBUG OPTION. Print the code's intermediate representation after the
+optimization and finalization passes to stdout before generating the
+binary. The instructions will be enumerated, and values will contain a
+list of liferanges.
.SH COMPILE WARNINGS
.TP
.B -Wunused-variable
Enable utf8 characters. This allows utf-8 encoded character constants,
and escape sequence codepoints in the valid utf-8 range. Effectively
enabling escape sequences like '\\{x2211}'.
+.TP
+.B -fbail-on-werror
+When a warning is treated as an error, and this option is set (which
+it is by default), it is like any other error and will cause
+compilation to stop. When disabling this flag by using
+\-fno-bail-on-werror, compilation will continue until the end, but no
+output is generated. Instead the first such error message's context is
+shown.
+.TP
+.B -floop-labels
+Allow loops to be labeled, and allow 'break' and 'continue' to take an
+optional label to decide which loop to actually jump out of or
+continue.

.SH OPTIMIZATIONS
.TP
.B -Opeephole
This will not have declared variables overlap, even if it was
possible.
.TP
+.B -Oglobal-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
Don't generate defs for immediate values or even declared constants.
Meaning variables which are implicitly constant or qualified as such
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
+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
+unnecessary copying and unnecessary temporary values. This
+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
+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.
.SH CONFIG
The configuration file is similar to regular .ini files. Comments
start with hashtags or semicolons, sections are written in square
