Ulrich Weigand 35668cc401 A number of test cases assume that an "int" parameter or return value
will be represented in the IR as a plain "i32" type.  This causes the
tests to spuriously fail on platforms where int is not a 32-bit type,
or where the ABI requires attributes like "signext" or "zeroext" to
be used.

This patch adds -triple or -target parameters to force those tests
to use the i386-unknown-unknown target.

Eli Friedman 1b125c3e31 Make FunctionDecl::doesDeclarationForceExternallyVisibleDefinition use the same logic as FunctionDecl::isInlineDefinitionExternallyVisible to figure out whether to emit a definition. Based on work by Anton Yartsev.

Nick Lewycky ba4cc01a1f Don't crash when codegen'ing an empty redecl of a function in C99 mode, when
neither was inline. Fixes bug introduced in r135377.

Douglas Gregor a700f68828 Reinstate the optimization suppressing available_externally functions
at -O0. The only change from the previous patch is that we don't try
to generate virtual method thunks for an available_externally
function.

Douglas Gregor dbb2806a7b Do not generate LLVM IR for available_externally function bodies at
-O0, since we won't be using the definitions for anything anyway. For
lib/System/Path.o when built in Debug+Asserts mode, this leads to a 4%
improvement in compile time (and suppresses 440 function bodies).

Douglas Gregor 299d76e901 Rework the way we determine whether an externally visible symbol is
generated for an inline function definition, taking into account C99
and GNU inline/extern inline semantics. This solution is simpler,
cleaner, and fixes PR4536.

Douglas Gregor 76fe50c654 Improve compatibility with GCC regarding inline semantics in GNU89
mode and in the presence of __gnu_inline__ attributes. This should fix
both PR3989 and PR4069.

As part of this, we now keep track of all of the attributes attached
to each declaration even after we've performed declaration
merging. This fixes PR3264.

Eli Friedman 2b680b43e9 Simplify the scheme used for keywords, and change the classification
scheme to be more useful.

The new scheme introduces a set of categories that should be more 
readable, and also reflects what we want to consider as an extension 
more accurately.  Specifically, it makes the "what is a keyword" 
determination accurately reflect whether the keyword is a GNU or 
Microsoft extension.

I also introduced separate flags for keyword aliases; this is useful 
because the classification of the aliases is mostly unrelated to the 
classification of the original keyword.

This patch treats anything that's in the implementation 
namespace (prefixed with "__", or "_X" where "X" is any upper-case 
letter) as a keyword without marking it as an extension.  This is 
consistent with the standards in that an implementation is allowed to define 
arbitrary extensions in the implementation namespace without violating 
the standard. This gets rid of all the nasty "extension used" warnings 
for stuff like __attribute__ in -pedantic mode.  We still warn for 
extensions outside of the the implementation namespace, like typeof.
If someone wants to implement -Wextensions or something like that, we 
could add additional information to the keyword table.

This also removes processing for the unused "Boolean" language option; 
such an extension isn't supported on any other C implementation, so I 
don't see any point to adding it.

The changes to test/CodeGen/inline.c are required because previously, we 
weren't actually disabling the "inline" keyword in -std=c89 mode.

I'll remove Boolean and NoExtensions from LangOptions in a follow-up 
commit.

Douglas Gregor 89c8e000cf Fix handling of C99 "extern inline" semantics when dealing with

Chris Lattner f8dc07369a Fix some mishandling of the attr(gnu_inline) mode when used with
extern.  Previously we would warn about it and ignore the attribute.
This is incorrect, it should be handled as a c89 "extern inline" 
function.  Many thanks to Matthieu Castet for pointing this out and
beating me over the head until I got it.
