mycroft 6ec13b9d73 Return an error when there are too many segments rather than abort()ing.
This way `ldd /usr/libexec/ld.elf_so' doesn't core dump.

chs 871e0c1533 switch back to using a file mapping for the initial mapping of a new object.
this allows the kernel to use PMAP_PREFER() to give us better alignment on
platforms that care.

mycroft 305c949781 Changes from msaitoh to fix local/global symbol confusion, and to fix weak
symbol support -- updated by me for elf.h changes.

erh 6752f572d8 Remove ELFNAME defines since they are defined in sys/exec_elf.h 1999-11-04 02:00:17 +00:00
kleink 522cbf0248 Update to match new SVR4-style definition names in <sys/exec_elf.h>. 1999-10-25 13:55:06 +00:00
hannken db05621dec Undo last change. While these macros are defined in exec_elf.h, they are
enclosed by `#ifdef _KERNEL'.

erh b11baa5513 Remove ELFNAME macros which are already defines in exec_elf.h 1999-10-21 21:15:04 +00:00
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).

jonathan 20d6ace077 Mipsel changes to ELF ldd/ld.so:
* don't abort() on NetBSD/pmax 1.1 elf binaries;
  * Assume 32-bit elf unless compiling for Alpha;
  * note bugs in ldd's README.

cgd 41fe218b25 First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.).  This runs, but it's
in serious need of cleaning and/or a fair bit of reworking.  See the README
file for more information, and a list of things to do.
