NAME

bcc-cc1 — C compiler backend

SYNOPSIS

DESCRIPTION

Bcc-cc1 is the backend for the bcc(1) C compiler.

It understands the following options:

-0

(the digit 0) 8086 target (works even on 80386 host)

-3

80386 target (works even on 8086 host)

-D

define

-E

produce preprocessor output

-I

include search path

-P

produce preprocessor output with no line numbers

-c

produce code with caller saving regs before function calls

-d

print debugging information in assembly output

-f

produce code with 1st argument passed in a register

-l

produce code for 2 3 1 0 long byte order (only works in 16-bit versions)

-o

assembler output file name follows

-p

produce (almost) position-independent code

-t

print source code in assembly output

-w

print what cc1 thinks is the location counter in assembly output

All the options except -D, -I and -o may be turned off by following the option letter by a ‘-’. Options are processed left to right so the last setting has precedence.

The following is defined before option processing:

__BCC__			1

The following may be defined after option processing:

__AS09__		1 if 6809 version
__AS386_16__		1 if -0 option on 80*86
__AS386_32__		1 if -3 option on 80*86
__CALLER_SAVES__	1 if -c option
__FIRST_ARG_IN_AX__	1 if -f option on 80*86
__FIRST_ARG_IN_X__	1 if -f option on 6809
__LONG_BIG_ENDIAN__	1 if -l option
__POS_INDEPENDENT__	1 if -p option on 6809

The following are standard builtins:

__FILE__ stringized name of current input file __LINE__ current line number
