Chris Lattner a0e871901b simplify code that creates SubtargetFeatureInfo, ensuring that features 
that are only used by MnemonicAliases will be found.

llvm-svn: 117844
 2010-10-30 20:07:57 +00:00
Chris Lattner 25896af4bb fix a fixme in stringmatcher, having it generate nice looking code if the 
'tomatch' code contains \n's.

Argyrios Kyrtzidis d3f0054395 Emit an error when trying to form a pointer-to-member to a bitfield. 
As a bonus, avoids a crash on the IRGen side due to accepting invalid code.

Argyrios Kyrtzidis 52355c8020 renamed: test/SemaCXX/ptrtomember-badcall.cpp -> test/SemaCXX/ptrtomember.cpp

Chris Lattner f9ec2fb34a fix typos and some serious bugs in feature handling (but not for 
cases that are currently exercised).  Thanks to Frits van Bommel for
the great review!

Chris Lattner aac142cc06 Resolve a terrible hack in tblgen: instead of hardcoding 
"In32BitMode" and "In64BitMode" into tblgen, allow any
predicate that inherits from AssemblerPredicate.

 2010-10-30 19:38:20 +00:00
Chris Lattner 2cb092dc55 Implement (and document!) support for MnemonicAlias's to have Requires 
directives, allowing things like this:

def : MnemonicAlias<"pop", "popl">, Requires<[In32BitMode]>;
def : MnemonicAlias<"pop", "popq">, Requires<[In64BitMode]>;

Move the rest of the X86 MnemonicAliases over to the .td file.

Daniel Dunbar cda8eb7a21 Revert r117678, "Qualified 'id' should implement all of static class type's", it breaks things.

Chris Lattner cf9b6e3107 diagnose targets that define two alises with the same 'from' mnemonic 
with a useful error message instead of having tblgen explode with an 
assert.

 2010-10-30 18:56:12 +00:00
Chris Lattner 477fba4f54 emit the mnemonic aliases in their own helper function instead of 
inline into MatchInstructionImpl.

for shl.  Caught by inspection.

Chris Lattner ba7b4fea97 implement (and document!) the first kind of MC assembler alias, which 
just remaps one mnemonic to another.  Convert a few of the X86 aliases
from .cpp to .td code.

Benjamin Kramer 4ab36ba726 Turns out that we may end up calling dladdr on GetExecutablePath, give it external linkage to make sure the lookup works on all platforms.

Duncan Sands e659aba516 Now that the MallocInst no longer exists, this workaround for 
it claiming not to have side-effects is no longer needed.

Duncan Sands b8f3b14dfb If a function does a volatile load from a global constant, do not 
consider it to be readonly.  In fact, don't even consider it to be
readonly if it does a volatile load from an AllocaInst either (it
is debatable as to whether readonly would be correct or not in this
case; play safe for the moment).  This fixes PR8279.

John McCall c273f24196 Better solution: calculate the visibility of functions and variables 
independently of whether they're definitions, then teach IR generation to
ignore non-explicit visibility when emitting declarations.  Use this to
make sure that RTTI, vtables, and VTTs get the right visibility.

John McCall 36cd5cc150 GCC faithfully calculates visibility for variables independently of 
whether it's a declaration or not, then ignores that information for
declarations unless it was explicitly given.  It's not totally clear
how that should be mapped into a sane system, but make an effort.

Sean Callanan 5a477cfd90 Added a hack that allows expressions to ignore 
Objective-C member accessibility restrictions.
Ultimately Clang should have a flag that ignores
accessibility for Objective-C like it has one
for C++.
