cs_create_smart if using dwarf information and external assembler
debug information as this is not compatible.
* Added a different message for cs_create_smart.
git-svn-id: trunk@19065 -
smartlink creation if using external assembler and Dwarf debugging
* Call CheckOptionsCompatibility again after setting currentt assembler

FreeB-licensed SGI version
* deleted constants that belong in glext.pp (and which are already
defined there)
* replaced "This is UNPUBLISHED PROPRIETARY SOURCE CODE of Silicon
Graphics, Inc." license header with FreeB license; see

Every startup code must now provide an additional entry point called "_dynamic_start" that is set as new the entry point if the program links to a Pascal shared library. Its purpose is to set up an exit hook usually passed via a register, which should be called during program finalization if non-nil.
We use this additional entry point because this register only has meaningful content when there are any compile-time linked shared libraries, otherwise it often contains random garbage. The difference between the _dynamic_start and the original code is minimal; actually in all implementations the _dynamic_start code passes on control to the old startup code, so we use an additional entry point instead of an additional startup file.
Detailed changes and fixes list:
compiler:
always link to the dynamic loader (ld.so) when compiling shared libraries. Fixes crashes in the loader during shared library finalization on some Linuxes
remove additional ENTRY() section in arm linker script
select either _dynamic_start or _start as entry point depending on whether this is a static or dynamic executable
powerpc*:
do not set System.isLibrary in startup code, it will be set during library initialization anyway
trap in case of reaching code locations that should not be reached instead of looping (possibly endlessly)
powerpc:
register atexit() function pointer if supplied to the executable and call it during shutdown
correctly set argc/argv/envp in shared library code and return correctly to the caller after initialization
pass on exitcode in shared library haltproc
use the more recent exit_group system call if available for shutdown
powerpc64
fix .ptrgl stub, do not set the environment register to the value of the GOT entry in the function descriptor
arm
do not set System.isLibrary in startup code, it will be set during library initialization anyway
reload exitcode to pass to shutdown
mips,mipsel,sparc
added stubs to allow correct linking
