type-check. Previously, we would see the error and then, effectively,
skip tokens until the end of the statement.

The result should be more useful recovery, both in the normal case

it also helps code completion do a much better job, because we do
"real" code completion on the right-hand side of an invalid binary
expression rather than completing with the recovery completion. For
example, given

  x = p->y

if there is no variable named "x", we can still complete after the p->
as a member expression. Along the recovery path, we would have
completed after the "->" as if we were in an expression context, which
is mostly useless.

14 years agoDriver: Add magic handling for "reserved library names", starting with
Daniel Dunbar [Fri, 17 Sep 2010 00:45:02 +0000 (00:45 +0000)]
Driver: Add magic handling for "reserved library names", starting with
-lstdc++. This is the best gross solution for a gross problem.

This issue is that historically, GCC has add -L options to its internally
library directories. This has allowed users and platforms to end up depending on
the layout of GCC's internal library directories.

We want to correct this mistake by eliminating that -L, but this means that
existing libraries which are in the GCC lib dir won't be found. We are going to
handle this by treating those -l names as "reserved", and requiring toolchains
to know how to add the right full path to the reserved library.

The immediately side effect of this is that users trying to use -L to find their
own -lstdc++ will need to start using -nostdlib (which is a good idea
anyway). Another side effect is that -stdlib=libc++ -lstdc++ will now do the
"right" thing, for curious definitions of right.

14 years agoImplement bracket insertion for Objective-C instance message sends as
Douglas Gregor [Wed, 15 Sep 2010 14:51:05 +0000 (14:51 +0000)]
Implement bracket insertion for Objective-C instance message sends as
part of parser recovery. For example, given:

  a method1:arg];

we detect after parsing the expression "a" that we have the start of a
message send expression. We pretend we've seen a '[' prior to the a,
then parse the remainder as a message send. We'll then give a
diagnostic+fix-it such as:

fixit-objc-message.m:17:3: error: missing '[' at start of message
      send expression
  a method1:arg];
  ^
  [

The algorithm here is very simple, and always assumes that the open
bracket goes at the beginning of the message send. It also only works
for non-super instance message sends at this time.

Disallow the use of UnknownVal as the index for ElementRegions.  UnknownVals can be used as
the index when the value evaluation isn't powerful enough.  By creating ElementRegions with
UnknownVals as the index, this gives the false impression that they are the same element, when
they really aren't.  This becomes really problematic when deriving symbols from these regions
(e.g., those representing the initial value of the index), since two different indices will
get the same symbol for their binding.

This fixes an issue with the idempotent operations checker that would cause two indices that
are clearly not the same to make it appear as if they always had the same value.
