A small patch to ld-elf2flt.in, that lets an elf2flt-ified toolchain run
from a directory other than that specifed in the original ./configure.
Helpful if you distribute toolchains and can't control where people
install them! :) Also helpful if you are testing toolchains and need to
move them around after the elf2flt "make install".

A slightly updated configure script
Greg Ungerer [Tue, 11 Nov 2003 07:23:04 +0000 (07:23 +0000)]
Find attached the patch for the elf2flt utility. Except the elf2flt.c file, I have slightly modified the Makefile.in. The reason for this is to check the target architecture and if it is set to "e1", another linker script is installed. The reason for this alchemy is that our linker needs some sections that are included in the e1-elf2flt.ld script.

I've found the bug! A BSS link-once section was missing in elf2flt.ld.
The old version of GCC probably didn't ever generate this kind of
section because it was placing everything in the data link-once section.

this patch adds Cygwin support to elf2flt. Also include a copy

This is just a cleaned-up version of Leon's former Cygwin patch

it doesn't break anything on Linux :-)

Fixed handling of MICROBLAZE_32 reloc type. The mb-gcc distributes
relocations across several places - the "standard" ones such as
q->addend and bfd_section_vma(), but also embeds small offsets in the
actual text (code) itself. Thus, it is necessary to examine the text to
get an initial offset, then add that to the others to get the final
fixup location.
This is required for at least MICROBLAZE_64 and MICROBLAZE_32 - others
may also need it.

Multiple sections of a given type are combined, and any holes between
sections are filled with zeroes.
This changes the definition of `text', `data', and `bss' to use the
flags set by BFD, rather than requiring hardwired input section names
(for the normal case where one is using GNU ld and the elf2flt.ld linker
script, this should produce identical results, as that only ever
produces the three well-defined sections anyway).

This capability was already sort of in the code, but intertwined with

Added support for the Microblaze archiecture.
The only mod outside the #ifdef TARGET_microblaze stuff in elf2flt.c is a new

arm expects the data segment on a 32 byte boundary, otherwise the GOT
