kleink 83265a56f2 Bump text alignments to 4 bytes. 1999-08-23 09:13:25 +00:00
matt 741f18b695 Initial VAX ELF32 support (mostly untested). It's checked primarily for
testing and archival for now.  I don't expect anyone to work with it
since the binutils and gas changes are still pending.  But you got to
crawl before you walk.

thorpej 5c5817ee4a When allocating the entire address space of an object, map an anonymous
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.

The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.

This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

kleink 1cc052ce00 Rearrange the shared library search path precedences to LD_LIBRARY_PATH >
runpath > built-in default; this is the behaviour of the SVR4 shared loader,
and gives users the opportunity to override the runpath.  (Addresses a report
on current-users by John Kohl.)

thorpej 4d256c199f When dlopen()'ing a shared object without an absolute pathname, search
for it in the rpath of the main program as well as the path specified
in LD_LIBRARY_PATH.

thorpej 206408b533 Protect certain definitions from view by crt0, by wrapping them in
#ifdef _RTLD_SOURCE.

Should fix the "variable page size" build error of crt0 on the SPARC.

christos 00e5621847 We need to compile with -DVARPSZ, because the sparc has a variable page
size depending on arch. Make it an error to compile without it. This
caused -lposix linked programs to fail.

thorpej adadf5ecc7 Don't even make depend if we're not going to build ld.elf_so. this is
especially important if the assembler syntax is different.

kleink 4b749d888f Always use ${MACHINE_ARCH} rather than ${MACHINE}, and reorder architectures
a bit.

kleink 75030fa2ee Add m68k code. 1999-04-29 15:06:41 +00:00
thorpej 44672d5287 Simplify _rtld_start() a little, and shave some cycles. Spefically, there's
no need to save the stack pointer.  Just push the space for the cleanup
and obj_main pointers before calling _rtld(), and pop it after loading those
pointers into the appropriate argument registers for the program entry point.
