fpc/rtl
History
sergei 06192a8137 Values of managed variables are never ever used after decrementing reference on the variable, so there is no point of having a 'decrement reference' as a separate operation. We can always do 'finalize', i.e. clear the contents after decref. 
* Modified fpc_ansistr_decr_ref and fpc_widestr_decr_ref so they always zero the pointer passed by reference. Other _decr_ref helpers already do it.
- Removed tcg.g_decrrefcount, calling cg.g_finalize instead.
- finalize_data_node and tcg.g_finalize: removed code generation for zeroing locations, because it is now done by RTL helpers. This further reduces code size.

As a total result of this change and r20118, the size of Lazarus executable is reduced by about 12%.

README.txt 

This is the Run-Time Library (RTL) tree for Free Pascal.

To recompile the RTL, edit the main makefile. The makefiles NEED a GNU make
compatible make, they need unix-like 'rm' and 'mv' commands, as well as some
others. You can find these in the gnuutils package on the ftp site.

The main makefile is located ABOVE the RTL tree. It uses the FPC
makefile.fpc to guess reasonable defaults for everything it needs.
(these files can be found in base.zip on the FTP site)

The only variable that you may want to set are
FPC             - What compiler to use. Use an absolute path. 
                  (default is ppc386)
INSTALL_UNITDIR - Where to install the RTL units 
OPT             - any special options you want to set for the compiler.

In principle, you can also descend into the subdirectory of your OS, and
type 'make' there, that should also compile everything.

The tree contains subdirectories for all the supported operating systems,
as well as all processor architectures. The processor directories contain
low-level routines which are required for the system unit (if they are not 
available in high-level language form), as well as optimized versions of
the pascal generic routines (the generic routine source code is localed in
the inc subdirectory).

The following directories are not supported officially and may not work
correctly with FreePascal v1.0:

go32v1 - The DJGPP go32v1 DOS extender (no longer supported)
palmos - The PalmOS directory for the Dragonball (incomplete)


Enjoy.
