| 2112 | =head1 NAME
|
|---|
| 2113 |
|
|---|
| 2114 | B::C - Perl compiler's C backend
|
|---|
| 2115 |
|
|---|
| 2116 | =head1 SYNOPSIS
|
|---|
| 2117 |
|
|---|
| 2118 | perl -MO=C[,OPTIONS] foo.pl
|
|---|
| 2119 |
|
|---|
| 2120 | =head1 DESCRIPTION
|
|---|
| 2121 |
|
|---|
| 2122 | This compiler backend takes Perl source and generates C source code
|
|---|
| 2123 | corresponding to the internal structures that perl uses to run
|
|---|
| 2124 | your program. When the generated C source is compiled and run, it
|
|---|
| 2125 | cuts out the time which perl would have taken to load and parse
|
|---|
| 2126 | your program into its internal semi-compiled form. That means that
|
|---|
| 2127 | compiling with this backend will not help improve the runtime
|
|---|
| 2128 | execution speed of your program but may improve the start-up time.
|
|---|
| 2129 | Depending on the environment in which your program runs this may be
|
|---|
| 2130 | either a help or a hindrance.
|
|---|
| 2131 |
|
|---|
| 2132 | =head1 OPTIONS
|
|---|
| 2133 |
|
|---|
| 2134 | If there are any non-option arguments, they are taken to be
|
|---|
| 2135 | names of objects to be saved (probably doesn't work properly yet).
|
|---|
| 2136 | Without extra arguments, it saves the main program.

|
|---|
| 2140 | =item B<-ofilename>
|
|---|
| 2141 |
|
|---|
| 2142 | Output to filename instead of STDOUT
|
|---|
| 2143 |
|
|---|
| 2144 | =item B<-v>
|
|---|
| 2145 |
|
|---|
| 2146 | Verbose compilation (currently gives a few compilation statistics).
|
|---|
| 2147 |
|
|---|
| 2148 | =item B<-->
|
|---|
| 2149 |
|
|---|
| 2150 | Force end of options
|
|---|
| 2151 |
|
|---|
| 2152 | =item B<-uPackname>
|
|---|
| 2153 |
|
|---|
| 2154 | Force apparently unused subs from package Packname to be compiled.
|
|---|
| 2155 | This allows programs to use eval "foo()" even when sub foo is never
|
|---|
| 2156 | seen to be used at compile time. The down side is that any subs which
|
|---|
| 2157 | really are never used also have code generated. This option is
|
|---|
| 2158 | necessary, for example, if you have a signal handler foo which you
|
|---|
| 2159 | initialise with C<$SIG{BAR} = "foo">. A better fix, though, is just
|
|---|
| 2160 | to change it to C<$SIG{BAR} = \&foo>. You can have multiple B<-u>
|
|---|
| 2161 | options. The compiler tries to figure out which packages may possibly
|
|---|
| 2162 | have subs in which need compiling but the current version doesn't do
|
|---|
| 2163 | it very well. In particular, it is confused by nested packages (i.e.
|
|---|
| 2164 | of the form C<A::B>) where package C<A> does not contain any subs.
|
|---|
| 2165 |
|

|---|
| 2190 | =item B<-f>
|

| 2191 |
|
|---|
| 2192 | Force options/optimisations on or off one at a time. You can explicitly
|
|---|
| 2193 | disable an option using B<-fno-option>. All options default to
|
|---|
| 2194 | B<disabled>.

|

|
|---|
| 2246 | Some C compilers impose an arbitrary limit on the length of string
|

| 2247 | constants (e.g. 2048 characters for Microsoft Visual C++). The
|
|---|
| 2248 | B<-llimit> options tells the C backend not to generate string literals
