Log Message:
gcc.old: vax: PR port-vax/57646 patch provided by Kalvis Duckmanton [21/21]

Define separate instruction patterns for extzv for the cases where the fiel
d width and offset happen to be a multiple of a byte or word.

If in PIC mode, and the source operand to extzv is a memory
reference, and the address of the memory location is an external
symbol, load the address into a temporary register before expanding
the instruction.

Adjust the constraints to the zero_extract instruction pattern to
disallow indexed source operands, as the VAX extzv instruction
computes offsets based on the size of a byte (not a word or a
longword)

Log Message:
gcc.old: PR port-vax/57646 patch provided by Kalvis Duckmanton [13/21]

Bitfield instructions will generate a reserved operand fault if the
operands are not reasonable (size > 32, position > 31 and size not
zero and field in a register). GCC generates code to test for these
conditions but in certain circumstances, the optimiser may decide
that a bitfield extraction instruction is invariant and move it
ahead of the instructions testing its arguments.

Introduce a new target hook to indicate to GCC that a bitfield
instruction may trap and update may_trap_p_1()

XXXRO: Although this patch includes diffs outside gcc/config/vax,
NFC for !TARGET_BITFIELD_MAY_TRAP_P, i.e., other than vax.

Log Message:
gcc.old: PR port-vax/57646 patch provided by Kalvis Duckmanton [13/21]

Bitfield instructions will generate a reserved operand fault if the
operands are not reasonable (size > 32, position > 31 and size not
zero and field in a register). GCC generates code to test for these
conditions but in certain circumstances, the optimiser may decide
that a bitfield extraction instruction is invariant and move it
ahead of the instructions testing its arguments.

Introduce a new target hook to indicate to GCC that a bitfield
instruction may trap and update may_trap_p_1()

XXXRO: Although this patch includes diffs outside gcc/config/vax,
NFC for !TARGET_BITFIELD_MAY_TRAP_P, i.e., other than vax.

thanks.  surprised it was needed for .old, but not surprised
the for GCC 12 -- that one had sanitizers replaced and i did
not attempt to merge, but re-ported.

it was pretty crazy -- our GCC 10 has a much nicer libsanitizer
than GCC 10 upstream, but GCC 12 has upgraded to an even newer
version that included many, but not all, of the netbsd fixes,
and finding all the fixes from the prior is difficult, as there
was no real "base version" to compare against parts of both GCC
and llvm upstreams were that base..

anyway, i say this because there's always a chance of something
else having been missed in the re-port.

thanks again!

gcc: Fix peephole optimization bug for sh3 (PR port-sh3/56311)

Cherry-picked from upstream:
https://gcc.gnu.org/git/gitweb.cgi?p=gcc.git;h=4dbb3af1efe55174a714d15c2994cf2842ef8c28
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=101469

Now, the PR confirmed fixed. No regression observed for full ATF run on
landisk (compared with GCC built with this peephole optimization being
removed by hand).

We thank Oleg Endo, the author of the upstream commit.

Also thanks hgutch@ and uwe@ for analysis.

Log Message:
Compiling some files with -fPIC and -O2 ends up having global

relocations "movl *psp, %rx" (/bin/sh parse.c). Treat pic code as

Log Message:
remove our riscv changes in gcc.old.  they were obsolete with GCC 5
update, let alone GCC 6.  new GCC 7 has native support again.

this is really about trying to avoid conflicts when we next have
gcc become gcc.old.

Log Message:
Cherry-pick upstream patch for internal_mmap() in GCC(.old) sanitizers

Fix internal_mmap() on 32-bit NetBSD platforms

There is need to use internal_syscall64() instead of internal_syscall_ptr().
The offset argument of type off_t is always 64-bit.

src/external/gpl3/gcc.old/dist/gcc/config/i386: i386.c

Log Message:
Apply upstream patch:
Incorrect codegen from rdseed intrinsic use (CVE-2017-11671)

We should not expand call arguments in between flags reg setting and
flags reg using instructions, as it may expand with flags reg
clobbering insn (ADD in this case).

Attached patch moves expansion out of the link. Also, change
zero-extension to non-flags reg clobbering sequence in case we perform
zero-extension with and.

CVS commit: src/external/gpl3/gcc.old/dist/gcc/config/i386

[Maya Rashish]

Module Name:src
Committed By:   maya
Date:   Fri Jul 28 22:24:27 UTC 2017

Modified Files:
src/external/gpl3/gcc.old/dist/gcc/config/i386: i386.c

Log Message:
Apply upstream patch:
Incorrect codegen from rdseed intrinsic use (CVE-2017-11671)

We should not expand call arguments in between flags reg setting and
flags reg using instructions, as it may expand with flags reg
clobbering insn (ADD in this case).

Attached patch moves expansion out of the link. Also, change
zero-extension to non-flags reg clobbering sequence in case we perform
zero-extension with and.
