add some final random notes, I've completed my pass over all the commits.
...
I'll work on turning this into something intelligible tomorrow.
llvm-svn: 145177
2011-11-27 08:32:32 +00:00
410f3d7f5d
The llvm.atomic intrinsics *were* removed in LLVM 3.0 (in r141333), remove the
...
autoupgrade logic for 2.9 and before.
llvm-svn: 145176
2011-11-27 08:18:55 +00:00
ee471c484a
remove autoupgrade support for old forms of llvm.prefetch and the old
...
trampoline forms. Both of these were correct in LLVM 3.0, and we don't
need to support LLVM 2.9 and earlier in mainline.
llvm-svn: 145174

llvm-svn: 145173
2011-11-27 07:37:53 +00:00
bc639298e5
remove asmparsing and documentation support for "volatile load", which was only produced by LLVM 2.9 and earlier. LLVM 3.0 and later prefers "load volatile".
...
llvm-svn: 145172
2011-11-27 06:56:53 +00:00
6a144a2227
Upgrade syntax of tests using volatile instructions to use 'load volatile' instead of 'volatile load', which is archaic.

2011-11-27 06:24:49 +00:00
90ef78c07f
remove autoupgrade support for really old-style debug info intrinsics.
...
I think this is the last of autoupgrade that can be removed in 3.1.
Can the atomic upgrade stuff also go?
llvm-svn: 145169
2011-11-27 06:18:33 +00:00
800b2b42ed
Use libcxx makefile's do-installhdrs target. <rdar://problem/10397739>
...
llvm-svn: 145168
2011-11-27 06:13:25 +00:00

llvm-svn: 145167
2011-11-27 06:10:54 +00:00
db89153969
remove autoupgrade support for LLVM 2.9 exception stuff. Mainline supports
...
LLVM 3.0 and later.
llvm-svn: 145165
2011-11-27 05:56:16 +00:00
1c9e5678b8
remove support for reading llvm 2.9 .bc files. LLVM 3.1 is only compatible back to 3.0
...
llvm-svn: 145164

8a3c663e95
Refactor libcxx makefile. No functional changes intended.
...
Besides cleaning up the repetition in the installhdrs target, the point of this
change is to provide a separate do-installhdrs target that can be used directly
from clang's runtime/libcxx makefile to install a copy of the headers along
with clang. <rdar://problem/10397739>
llvm-svn: 145162
2011-11-27 05:39:58 +00:00
97b3da5433
Add several new instructions supported by the latest MicroBlaze.
...
These instructions are not generated by the backend yet, this will come in a later commit.
llvm-svn: 145161
2011-11-27 05:16:58 +00:00
8e6d9da04c
Partially revert r145157 to quiet an unhappy buildbot.
...
Removing that buildbot would be a better solution, but this is at least
a temporary workaround.
llvm-svn: 145160
2011-11-27 01:48:54 +00:00
d2e2e1782f
Optimize comparison against 0 in conditional instructions.
...
Fix a couple of 80-column violations.
llvm-svn: 145159
2011-11-27 01:36:20 +00:00
9ffb97e631
Introduce a loop block rotation optimization to the new block placement
...
pass. This is designed to achieve one of the important optimizations
that the old code placement pass did, but more simply.
This is a somewhat rough and *very* conservative version of the
transform. We could get a lot fancier here if there are profitable cases
to do so. In particular, this only looks for a single pattern, it
insists that the loop backedge being rotated away is the last backedge
in the chain, and it doesn't provide any means of doing better in-loop
placement due to the rotation. However, it appears that it will handle
the important loops I am finding in the LLVM test suite.

51280d565b
Merge 128-bit and 256-bit X86ISD node types for VPERMILPS and VPERMILPD. Simplify some shuffle lowering code since V1 can never be UNDEF due to canonalizing that occurs when shuffle nodes are created.
...
llvm-svn: 145153

2011-11-26 21:50:38 +00:00
d086573a4d
Add the minimum implementation of cpuid.h. This works on "modern" intel cpus
...
and on clang, which seams to handled "=b" correctly even when ebx is the
PIC register.
llvm-svn: 145149
2011-11-26 20:53:19 +00:00
7704bd7ac3
Collapse X86ISD node types for PUNPCKH*, PUNPCKL*, UNPCKLP*, and UNPCKHP* to not be type specific. Now we just have integer high and low and floating point high and low. Pattern matching will choose the correct instruction based on the vector type.

and linux.

a84ad7d0d0
Fix APFloat::convert so that it handles narrowing conversions correctly; it
...
was returning incorrect values in rare cases, and incorrectly marking
exact conversions as inexact in some more common cases. Fixes PR11406, and a
missed optimization in test/CodeGen/X86/fp-stack-O0.ll.

Remove ZooLib from the projects list.

I don't see how the project is using LLVM and we really can't list every user of
the clang analyzer. Sorry.

In Microsoft mode, make "Unqualified lookup into dependent bases of class templates" works inside a friend function definition at class scope.
...
Basically we have to look into the parent *lexical* DeclContext for friend functions at class scope. That's because calling GetParent() return the namespace or file DeclContext.
This fixes all remaining cases of "Unqualified lookup into dependent bases of class templates" when parsing MFC code with clang.

d65a444478
Remove 256-bit specific node types for UNPCKHPS/D and instead use the 128-bit versions and let the operand type disinquish. Also fix the load form of the v8i32 patterns for these to realize that the load would be promoted to v4i64.

7adee1a01a
Fix a silly use-after-free issue. A much earlier version of this code
...
need lots of fanciness around retaining a reference to a Chain's slot in
the BlockToChain map, but that's all gone now. We can just go directly
to allocating the new chain (which will update the mapping for us) and
using it.
Somewhat gross mechanically generated test case replicates the issue
Duncan spotted when actually testing this out.

When adding blocks to the list of those which no longer have any CFG
...
conflicts, we should only be adding the first block of the chain to the
list, lest we try to merge into the middle of that chain. Most of the
places we were doing this we already happened to be looking at the first
block, but there is no reason to assume that, and in some cases it was
clearly wrong.
I've added a couple of tests here. One already worked, but I like having
an explicit test for it. The other is reduced from a test case Duncan
reduced for me and used to crash. Now it is handled correctly.

Add feature to diagnostics that will provide more information on function
...
pointer mismatch. Cases covered are: initialization, assignment, and function
arguments. Additional text will give the extra information about the nature
of the mismatch: different classes for member functions, wrong number of
parameters, different parameter type, different return type, and function
qualifier mismatch.
