to load an immediate that does not fit into 16-bit. Also, take into
consideration the global base register slot on the stack when computing the
stack size.

emits a series of instructions to load an immediate.

Long-branches need access to the global base register to get the destination
address.

This is the first of a series of patches which implements long branch expansion
for MIPS.

delay slot filler pass of MIPS, per suggestion of Jakob Stoklund Olesen.

This change, along with the fix in r158154, enables machine verification
to be run after delay slot filling.

test/Driver/warning-options.cpp: Mark as XFAIL:cygming. -pedantic is passed with gcc-as driver. PR12920

llvm-svn: 158423

This reduces the number of warnings generated by Doxygen by about 100
(roughly 10%).  Issues addressed:
(1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments
when they're not supposed to be Doxygen commands or links, and
similarly for "<baz>" when it's not intended as as HTML tag;
(2) Changed some \t commands (which don't exist) to \c ("to refer to a
word of code", as the Doxygen manual says);
(3) \precondition becomes \pre;
(4) When touching comments, deleted a couple of spurious spaces in them;
(5) Changed some \n and \r to \\n and \\r;
(6) Fixed one tiny typo: #pragms -> #pragma.

This patch touches documentation/comments only.

override whether headers are system headers by checking for prefixes of the
header name specified in the #include directive.

This allows warnings to be disabled for third-party code which is found in
specific subdirectories of include paths.

use a numeric constant for now so that we don't require an unreleased

out.

since then the entire expression must equal zero (similarly for other operations
with an absorbing element).  With this in place a bunch of reassociate code for
handling constants is dead since it is all taken care of when linearizing.  No
intended functionality change.

Fix intrinsics for XOP frczss/sd instructions. These instructions only take one source register and zero the upper bits of the destination rather than preserving them.

llvm-svn: 158396

Fix RecursiveASTVisitor to visit CXXForRangeStmts accordingly to visit
implicit or explicit code.

The key bug that inspired this was the Visitor not visiting the range
initializer of such a loop, which is explicit code.

This patch extends FoldBranchToCommonDest to fold unconditional branches.
For unconditional branches, we fold them if it is easy to update the phi nodes 
in the common successors.
