OptionValueFileSpec::SetValueFromCString() passes the c string to
FileSpec::SetFile(str, true /* resolve */) - and with Zachary's
changes to FileSpec we're using llvm::sys::fs::make_absolute() to
do that "resolve" action now, where we used to use realpath().

One important difference between llvm::sys::fs::make_absolute and
realpath is that when they're handed a filename (no directory),
realpath prepends the current working directory *and if the file exists*,
returns that full path.  If that file doesn't exist, the caller
uses the basename only.

llvm::sys::fs::make_absolute prepends the current working directory
regardless of whether it exists or not.

I considered having FileSpec::SetFile save the initial pathname,
call FileSpec::Resolve, and then check to see if the Resolve return
path exists - and if not, go back to the original one.

But instead I just went with changing 'target modules load' to treat its

Clarify the description of the noalias attribute

The previous description of the noalias attribute did not accurately specify

from that used by the C specification to define the semantics of restrict. For
the argument attribute, the semantics can be precisely specified in terms of
objects accessed through pointers based on the arguments, and this is now what
is done.

Saying that the semantics are 'slightly weaker' than that provided by C99
restrict is not really useful without further elaboration, so that has been
removed from the sentence.

noalias on a return value is really used to mean that the function is
malloc-like (and, in fact, we use this attribute to represent
__attribute__((malloc)) in Clang), and this is a stronger guarantee than that
provided by restrict (because it is a property of the pointed-to memory region,

The Syntax enumeration requires at least three bits to store all of its values. Increase the number of bits for SyntaxUsed. Decrease the number of expression arguments allowed by a single bit so that the bit fields continue to add up to 32-bits evenly.

There is no test for this fix because I could find no reasonable way to trigger a visible failure from it.

Thanks to Doug Gregor for spotting this!

10 years ago[PECOFF] Sort export table properly.
Rui Ueyama [Thu, 20 Nov 2014 21:05:05 +0000 (21:05 +0000)]
[PECOFF] Sort export table properly.

Export table entries need to be sorted in ASCII-betical order,
so that the loader can find an entry for a function by binary search.

We sorted the entries by its mangled names. That can be different
from their exported names. As a result, LLD produces incorrect export
table, from which the loader complains that a function that actually
exists in a DLL cannot be found.

This patch fixes that issue.

10 years agoFix a trip-count overflow issue in LoopUnroll.
Michael Zolotukhin [Thu, 20 Nov 2014 20:19:55 +0000 (20:19 +0000)]
Fix a trip-count overflow issue in LoopUnroll.

Currently LoopUnroll generates a prologue loop before the main loop
body to execute first N%UnrollFactor iterations. Also, this loop is
used if trip-count can overflow - it's determined by a runtime check.

However, we've been mistakenly optimizing this loop to a linear code for
UnrollFactor = 2, not taking into account that it also serves as a safe
version of the loop if its trip-count overflows.
