Gordon Henriksen fb56bde933 Noting and enforcing that GC intrinsics are valid only within a
function with GC.

This will catch the error when the inliner inlines a function with
GC into a caller with no GC.

Duncan Sands 8c5822802e Get the verifier to check attributes on calls as well
as on functions.  Make it verify invokes and not just
ordinary calls.  As a (desired) side-effect, it is no
longer legal to have call attributes on arguments that
are being passed to the varargs part of a varargs
function (llvm-as drops them on the floor anyway).

Duncan Sands b5a79d0eaa Make invokes of inline asm legal. Teach codegen
how to lower them (with no attempt made to be
efficient, since they should only occur for
unoptimized code).

Christopher Lamb edf0788758 Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

Christopher Lamb 55c6d4f22f Make it clear in the LangRef that allocation instructions only operated on the generic address space. Implement support in the verifier for ensuring this is true.

Duncan Sands ad0ea2d430 Fix PR1146: parameter attributes are longer part of
the function type, instead they belong to functions
and function calls.  This is an updated and slightly
corrected version of Reid Spencer's original patch.
The only known problem is that auto-upgrading of
bitcode files doesn't seem to work properly (see
test/Bitcode/AutoUpgradeIntrinsics.ll).  Hopefully
a bitcode guru (who might that be? :) ) will fix it.

Duncan Sands 185eeac0f8 Fix PR1816. If a bitcast of a function only exists because of a
trivial difference in function attributes, allow calls to it to
be converted to direct calls.  Based on a patch by Török Edwin.
While there, move the various lists of mutually incompatible
parameters etc out of the verifier and into ParameterAttributes.h.

Duncan Sands e0e774b6fd Don't barf on empty basic blocks. Do not rely on assert
doing something - this needs to work for release builds
too.  I chose to just abort rather than following the
fancy logic of abortIfBroken, because (1) it is a pain
to do otherwise, and (2) nothing is going to work if the
module is this broken.

Chris Lattner b6fc40e60f I am not sure this is a good idea to be an option, but rename the option for
now.  It conflicts with clang's -pedantic flag.

Gordon Henriksen a2f3e13cf4 Fix for PR1633: Verifier doesn't fully verify GC intrinsics
LLVM now enforces the following prototypes for the write barriers:

<ty>* @llvm.gcread(<ty2>*, <ty>**)
void @llvm.gcwrite(<ty>*, <ty2>*, <ty>**)

And for @llvm.gcroot, the first stack slot is verified to be an alloca or a 
bitcast of an alloca.

Fixes test/CodeGen/Generic/GC/lower_gcroot.ll, which violated these.

Chandler Carruth 7132e00de7 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future.
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

Reid Spencer b6508349a7 After a discussion with Anton, it turns out that the InReg attribute is not
permitted on function results. So, revert the last patch to make it illegal.

llvm-svn: 40632
2007-07-31 14:39:10 +00:00
Reid Spencer 160e4faedc The InReg parameter attribute is valid on function results. The llvm-gcc-4.0
front end converts regparm attribute on the gcc function into InReg attribute 
on the llvm function. This fixes test/CFrontend/2002-07-30-SubrefSetAssertion.c

llvm-svn: 40618
2007-07-31 06:33:37 +00:00
Duncan Sands 5d49bcdce0 It seems logical that InReg should be incompatible
with StructReturn and ByVal, so make it so.

Duncan Sands 07c9066238 As the number of parameter attributes increases,
Verifier::visitFunction is suffering a combinatorial
explosion due to the number of mutually incompatible
attributes.  This patch tidies the whole thing up
using attribute masks.  While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail.  Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).

2007-07-23 23:46:43 +00:00
Reid Spencer 6c2b393f0c Add better verification of attributes on function types. It is not permitted
to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.
