martin d7931a6191 Quote symbol names in a debug message (to make it easier to spot an empty 
symbol name, a common failure mode)

martin d977618dcf Backout -DDEBUG that I accidently commited with the last change 2005-01-11 07:47:37 +00:00
martin 0a1196da3e Add LD_BIND_NOW support for sparc and remove some relocation types that 
are not supposed to happen in 32bit code.
From Nick Hudson.

simonb c364c98f98 Don't process DT_DEBUG on MIPS as the dynamic section is mapped 
read-only.  DT_MIPS_RLD_MAP is used instead.

Patch from Nick Hudson.

martin 995d8a8e4b Add support for unaligned relocs on sparc, from PR 26858. 
Should also fix PR 25901 and PR 18296.

skrll 38fb01be3a Apply fixes from Charles: 
- Fix how _rtld_relocate_nonplt_self deals with REL32 relocations.

- Change the assert so that it is correct for binutils 2.14 and 2.15.

There are still problems with the libraries generated with binutils 2.15,
but at least ld.elf_so doesn't crash.

uwe 255de8f40e Preserve r2 in _rtld_bind_start - in r2 functions that return 
aggregate types are passed the address of the memory area to store the
returned result to.

Fixes PR port-sh3/26949.

rearnsha 3fa803b523 Check the type of symbols; if it's a Thumb function, then set the Thumb 
bit in the relocated value (JUMP_SLOT, ABS32 & GLOB_DAT).

thorpej 2a63e04007 - Change the strong dlfcn names in libc to ___name, and make the __name 
versions used by others in libc weak, so that we have:
	name: weak
	__name: weak
	___name: strong
- Add __name strong aliases of the dlfcn names in ld.elf_so, so that we have:
	name: strong
	__name: strong

This allows ld.elf_so to self-resolve both the name and __name variants
of the dlfcn functions, the former being required for dlfcn support in
applications, the latter being required for dlfcn support in libc.

Fixes the problem described in:

petrov 1ee4832b70 Don't print relocated content (in DEBUG mode) as it can cause 
misaligned access. It needs to be done differently if needed at all.
Fix PR port-sparc64/20907.

cube d1b3d841ee Make ld.elf_so use the new sysctl API. That allows the user to give any 
sysctl variable name in /etc/ld.so.conf.  It also makes the ld.elf_so
binary slightly smaller (at least on i386), and has no impact on
performance.

Fixes PR 26100.

skrll 701ae47cdf Fix the dynamic linker for hppa using ELF. 
Lazy binding doesn't work 100% of the time so force immediate binding.
One possible reason is that the PLT stub blows away r20 which the
compiler might not take into account.

lukem 130ab7336b Rework how MAKEVERBOSE operates: 
*	Don't bother prefixing commands with a line of  ${_MKCMD}\
	and instead rely upon "make -s".  This is less intrusive on
	all the Makefiles than the former.  Idea from David Laight.

    *	Rename the variables use to print messages.  The scheme now is:
	    _MKMSG_FOO		Run  _MKMSG 'foo'
	    _MKTARGET_FOO	Run  _MKMSG_FOO ${.TARGET}
	From discussion with Alistair Crooks.
