It fixed a test named tstack. Actually, Linux user get the stacktop is
incorrect in current. The value of stack pointer when enter the procedure
is thought as it is in the highest stack page. But if the parameters is
enough large, lager than 16k, most of arch will also fail this test.
Since the LoongArch default pagesize is 16k, it fail often because
stack-layout-randomization causes the stackpointer underflow to next page.
I had tried fixed it in rtl/linux/[arch]/si_*. But because the codes is
unworthy and hardly the parameters is enough large, just expand
STACK_MARGIN_MAX for simplicity.
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).
Enjoy.
