Re: 1997-11-22 egcs snapshot available

The reason egcs fails is because it's much better at finding loop
invariants than gcc-2.7.

As a result you end up with an asm like this:

(insn 37 34 39 (asm_operands/v ("movw $(( 1 << 3) - 1),%1
        movw %%ax,%2
        rorl $16,%%eax
        movb %%al,%3
        movb $0x82,%4
        movb $0x00,%5
        movb %%ah,%6
        rorl $16,%%eax") ("") 0[
            (symbol_ref:SI ("default_ldt"))
            (mem:QI (plus:SI (reg:SI 37)
                    (reg:SI 23)))
            (mem/s:QI (reg:SI 42))
            (mem/s:QI (reg:SI 41))
            (mem/s:QI (reg:SI 40))
            (mem/s:QI (reg:SI 39))
            (mem/s:QI (reg:SI 38))
        ]
        [
            (asm_input:SI ("a"))
            (asm_input:QI ("m"))
            (asm_input:QI ("m"))
            (asm_input:QI ("m"))
            (asm_input:QI ("m"))
            (asm_input:QI ("m"))
            (asm_input:QI ("m"))
        ]  ("k.c") 16) -1 (nil)
    (nil))

Note that this asm needs 7 hard registers, which is more than you can
count on being available on the x86.

So while we could probably disable the aggressive loop invariant detection,
it would just be papering over the real bug, which is the asm itself.

The diff file is now named egcs-971122-971114.diff.gz
                         new version ^ ^ old version

The previous diff files were named egcs-<oldversion>-<newversion>.

Is the change intentional ?

I'd prefer to keep the old convention, because the old version name
fit in my 14-character file names, whereas with the convention used
for 971122, the old version name falls outside of the 14 char limit,
and automated scripts can't work anymore.

No it was not intentional -- another goof because I couldn't use my
normal procedures.  The dates ended up reversed.  It'll take an hour
or so for the snapshot to rebuild with the correct ordering

You can get to the patch, but not the full thing.   And unless you 
know the full name of the patch (it's not hard to decude) you will
probably find it easier to go through the web version or just use
this URL.

ftp://ftp.cygnus.com/pub/egcs/snapshots/1997-11-22/egcs-971114-971122.diff.gz

The patch can be gotten.

My goof -- the normal snapshot procedures had to be severaly hacked because
my machine is still off the net.

I'll fix the tar.gz and diff.gz files, it'll take an hour or so to get them
rebuilt.

I turned off perms on the dir while I was fixing the version.c botch.

It should be accessable now.

Just a goof in the script which kept stuff from being installed correctly --
had to hack things since my machine is still off the net :(  Damn uswest.

Less :-)  The idea is barring any major goof's Wednesday's snapshot is the
release (minus doc stuff which I'll be working on over the holiday weekend).

The permission on the directory doesn't allow anything as of
Sun Nov 23 12:05:51 PST 1997.

Are you counting on having more or less help available over the holiday

1997-11-22 egcs snapshot available

[Jeffrey A Law]

egcs-ss-971122 is now available in ftp.cygnus.com:/pub/egcs/snapshots/1997-11-22
(and on various mirrors shortly, see the home page for mirror sites).

We expect to make one more snapshot (Wednesday) before the first release,
between now and then I'll be pouring over all the egcs testing info folks
have sent (thanks everyone!).  Hopefully we won't need to make any significant
changes between now and Wednesday.

I'll so be working on doc issues for this release most of the week.  I'm
hoping we can ship the first release by 11/30.

Changes in this snapshot:
        * Fix alpha config.guess problem, alpha-vms & alpha-nt bugs.

        * Minor fixes for systems with 14char filename limits.
        
        * Fix so g++ works with native assembler on hpux7,8,9

        * Workaround for conditional move bug on ppro.

        * More exception and flow graph fixes.

        * Fix PA codegen bug.

        * Fix FIXPROTO buglet on irix5

        * Minor CSE bugfixes.

        * Minor sco5 bugfixes.

        * Minor bugfixes for make compare/compare-lean.

        * Some MIPS codegen fixes.

        * Various C++ bugfixes.

        * Minor g77 & g77-runtime fixes.

        * Minor libio/libstdc++ bugfixes.
