History

mycroft b9c785bd44 As seen on tech-toolchain: So the problem is thus: * The {u,}mulsidi3 generate two parallel sets which modify the upper and lower halves of the target register. * life_analysis() does not track subregister modifications -- if you don't modify the whole register with a single set, it considers the register unused. The simple, if klugy, solution to this is to stick an explicit clobber in. It seems to work. While doing this, I noticed that constant folding was not happening for 32x32->64 multiplies. This is because the parallel set generated by {u,}mulsidi3 cannot be folded at all. To solve this, I first expand to a normal multiply, and then use a define_insn_and_split to convert it to the parallel set after CSE and constant folding. This patch has also been submitted to GCC bugzilla, but who knows if I'll get a reply to that.		2003-10-29 21:25:03 +00:00

HOW TO BUILD A CROSS COMPILER
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[Section to be written.]

See also: http://www.netbsd.org/Documentation/cross/


IMPORTED VERSIONS
~~~~~~~~~~~~~~~~~
The following software is in gnusrc/gnu/dist/toolchain, in a unified build
structure:

    gcc-2.95.3
    binutils-2.13.2.1
    gdb-5.0


IMPORT STEPS
~~~~~~~~~~~~
1. All distributions were unpacked and all `.cvsignore' files were
   removed.

2. All files in gcc's `include' top level directory were removed from
   binutils's `include' top level directory (these are the libiberty
   include files).

   cd gcc-*/include; for f in *; do rm -f ../../binutils-*/include/$f; done

3. The gcc distribution was imported in one shot into
   src/gnu/dist/toolchain, including the recursive build structure.

4. The binutils distribution was stripped down to the following directories,
   with no files at the top level:

   bfd, binutils, gas, gprof, include, intl, ld, opcodes

5. Binutils was imported into src/gnu/dist/toolchain, which included
   only the subdirectories above.

6. The gdb distribution was stripped down to the following directories,
   with no files at the top level:

   gdb, mmalloc, readline, sim

7. Gdb was imported into src/gnu/dist/toolchain, which included only
   the subdirectories above.
