# Defines (preprocessor)
# ----------------------

#
# nested #IFNDEF, #IFDEF, #ENDIF, #ELSE, #DEFINE, #UNDEF are allowed
#
# -d is the same as #DEFINE
# -u is the same as #UNDEF
#

# When not m68k is defined at the commandline, define i386
#IFNDEF m68k
  #DEFINE i386
#ENDIF

#
# Some examples (for switches see below, and the -? helppages)
#
# Try compiling with the -dRELEASE or -dDEBUG on the commandline
#

# For a release compile with optimizes and strip debuginfo
#IFDEF RELEASE
  -OG2p3
  -Xs
  #WRITE Compiling Release Version
#ENDIF

# For a debug version compile with debuginfo and all codegeneration checks on
#IFDEF DEBUG
  -g
  -Crtoi
  #WRITE Compiling Debug Version
#ENDIF

# ----------------
# Parsing switches
# ----------------

# All assembler blocks are intel styled by default
#-Rintel

# All assembler blocks are AT&T styled by default
#-Ratt

# Semantic checking
# -S2   switch some Delphi 2 extension on
# -Sc   supports operators like C (*=,+=,/= and -=)
# -Sg   allows LABEL and GOTO
# -Si   support C++ stlyed INLINE
# -Sm   support macros like C (global)
# -So   tries to be TP/BP 7.0 compatible
# -Ss   constructor name must be init (destructor must be done)
# -St   allows static keyword in objects

# Allow goto, inline, C-operators, C-vars
-Sgic

# Code generation
# ---------------

# Uncomment the next line if you always want static/dynamic units by default
# (can be overruled with -CD, -CS at the commandline)

# Set the default heapsize to 8Mb
#-Ch8000000

# Set default codegeneration checks (iocheck, overflow, range, stack)
#-Ci
#-Co
#-Cr
#-Ct

# Optimizer switches
# -Og        generate smaller code
# -OG        generate faster code (default)
# -Or        keep certain variables in registers (still BUGGY!!!)
# -Ou        enable uncertain optimizations (see docs)
# -O1        level 1 optimizations (quick optimizations)
# -O2        level 2 optimizations (-O1 + slower optimizations)
# -O3        level 3 optimizations (same as -O2u)
# -Op        target processor
#     -Op1  set target processor to 386/486
#     -Op2  set target processor to Pentium/PentiumMMX (tm)
#     -Op3  set target processor to PPro/PII/c6x86/K6 (tm)
