I believe the authors of GHC followed the naming conventions
of GCC, which can be gleaned from GCC's info page.
-warning-related options typically start with -W
-machine-independent flags that control optimization,
code-generation or language dialects start with -f.
Most flags have positive and negative forms.
-many pre-processor-related options start with -i
-hardware-dependent options start with -m, e.g.,
-mcpu=i686 -mno-fancy-math-387 -malign-int
-mno-power [RS/6000-related option]
-myellowknife [On embedded PowerPC systems, assume that the startup
module is called `crt0.o' and the standard C
libraries are `libyk.a' and `libc.a']
Of possible interest is a file
gcc-2.95.2/gcc/future.options
from GCC's source code. The file lists a few suggested options. The
file is an e-mail message from Noah Friedman to Richard Stallman, Jim
Blandy and a few other people. Some of the suggested options are:
-Waggravate-return
-Wcast-spell
-Wcaste-align [cf. the existing GCC option -Wcast-align]
-Win [I guess warn about the Windows system]
-Wmissing-protons
-Wredundant-repetitions
-antsy
-fbungee-jump
-fexpensive-operations [cf. -fexpensive-optimizations]
-fextra-strength [must be a negative form of -fstrength-reduce]
-fkeep-programmers-inline [cf. the existing option -fkeep-inline-functions]
-fjesus-saves [cf. the existing option -fcaller-saves]
-fno-peeping-toms [cf. the existing option -fno-peephole]
-fruit-roll-ups [cf. the existing option -funroll-loops]
-fshort-enough
-mno-dialogue
-vomit-frame-pointer
