53 one-line patch to perl itself. One or two of the programs in perl's

82 bytecode programs. It is *not* a standard perl+XSUB perl executable.
87 functional enough to compile almost the whole of the main perl test
90 In the following examples, you'll need to replace "perl" by
91     perl -Iblib/arch
94 "perl" by
95     ./perl
96 if you have built the extensions into a statically linked perl binary.
98 (1) To compile perl program foo.pl with the C backend, do
99     perl -MO=C,-ofoo.c foo.pl
100 Then use the cc_harness perl program to compile the resulting C source:
101     perl cc_harness -O2 -o foo foo.c
106     perl cc_harness -O2 -o foo -DBROKEN_STATIC_REDECL foo.c
110 arguments passed to your executable to be interpreted by perl (e.g. -Dx)
124 optimised C code for the execution path of your perl program), use
125     perl -MO=CC,-ofoo.c foo.pl
158 and with Linux/ELF, rebuild the perl .c files with -fPIC (and I
168 When you compile perl executables with cc_harness, append -L/usr/lib
169 otherwise the -L for the perl source directory will override it. For
171     perl -Iblib/arch -MO=CC,-O2,-ofoo3.c foo3.bench
172     perl cc_harness -o foo3 -O2 foo3.c -L/usr/lib
175 You'll probably also want to link your main perl executable against
176 libperl.so; it's nice having an 11K perl executable.
179     perl -MO=Bytecode,-ofoo foo.pl
185 as perl options. If you want to load chunks of bytecode into an already
186 running perl program then use the -m option and investigate the
192 (3) There are little Bourne shell scripts and perl programs to aid with
197     perl -MO=Terse,exec foo.pl
202     perl -MO=Debug foo.pl
206     perl -MO=Xref foo.pl
210 The C and CC backends can successfully compile some perl programs which

235 from running the same program with standard perl. Think of the compiler
242 perl behaviour if it's deemed proper and the resulting performance hit
243 is accepted. I'll use "standard perl" to mean the result of running a
244 Perl program using the perl executable from the perl distribution.
249     Standard perl calculates the target of "next", "last", and "redo"
261     with standard perl but gives a compile-time error with the compiler.
265     it behaves as a range or a flip/flop. Standard perl delays until
278     than standard perl. Operations on large numbers or on boundary
282     Features of standard perl such as $[ which have been deprecated
283     in standard perl since version 5 was released have not been
316 * Any "-w" option in the first line of your perl program is seen and
317   acted on by perl itself before the compiler starts. The compiler
318   itself then runs with warnings turned on. This may cause perl to
