# Pascal language mode
# -Mfpc free pascal dialect (default)
# -Mobjfpc switch some Delphi 2 extensions on
# -Mdelphi tries to be Delphi compatible
# -Mtp tries to be TP/BP 7.0 compatible
# -Mgpc tries to be gpc compatible
# -Mmacpas tries to be compatible to the macintosh pascal dialects
#
# Turn on Object Pascal extensions by default
#-Mobjfpc
# Assembler reader mode
# -Rdefault use default assembler
# -Ratt read AT&T style assembler
# -Rintel read Intel style assembler
#
# All assembler blocks are AT&T styled by default
#-Ratt
# Semantic checking
# -S2 same as -Mobjfpc
# -Sc supports operators like C (*=,+=,/= and -=)
# -Sa include assertion code.
# -Sd same as -Mdelphi
# -Se<x> error options. <x> is a combination of the following:
# <n> : compiler stops after the <n> errors (default is 1)
# w : compiler stops also after warnings
# n : compiler stops also after notes
# h : compiler stops also after hints
# -Sg allow LABEL and GOTO
# -Sh Use ansistrings
# -Si support C++ styled INLINE
# -Sk load fpcylix unit
# -SI<x> set interface style to <x>
# -SIcom COM compatible interface (default)
# -SIcorba CORBA compatible interface
# -Sm support macros like C (global)
# -So same as -Mtp
# -Sp same as -Mgpc
# -Ss constructor name must be init (destructor must be done)
# -St allow static keyword in objects
# -Sx enable exception keywords (default in Delphi/ObjFPC modes)
#
# Allow goto, inline, C-operators, C-vars

# Optimizer switches
# -Os generate smaller code
# -O1 level 1 optimizations (quick optimizations, debuggable)
# -O2 level 2 optimizations (-O1 + optimizations which make debugging more difficult)
# -O3 level 3 optimizations (-O2 + optimizations which also may make the program slower rather than faster)
# -Op<x> set target cpu for optimizing, see fpc -i for possible values

# See "fpc -i" also for more fine-grained control over which optimizations
