Hi all, Please review this patch. It's fixing PR3232 comment #8. Function bar from 2008-03-24-BitFiled-And-Alloca.c compiles to: %struct.Key = type { { i32, i32 } } ... define i32 @bar(i64 %key_token2) nounwind { entry: %key_token2_addr = alloca i64 ; <i64*> [#uses=2] %retval = alloca i32 ; <i32*> [#uses=2] %iospec =

How about this patch then? -bw Index: gcc/llvm-convert.cpp =================================================================== --- gcc/llvm-convert.cpp (revision 43658) +++ gcc/llvm-convert.cpp (working copy) @@ -758,7 +758,7 @@ } -Value *TreeToLLVM::Emit(tree exp, Value *DestLoc) { +Value *TreeToLLVM::Emit(tree exp, Value *DestLoc, unsigned Alignment) {

Ok, I've tracked down the problem I've had bootstrapping llvm-gcc. The culprit is in TreeToLLVM::EmitMemCpy: void TreeToLLVM::EmitMemCpy(Value *DestPtr, Value *SrcPtr, Value *Size, unsigned Align) { const Type *SBP = PointerType::get(Type::Int8Ty); const Type *IntPtr = TD.getIntPtrType(); Value *Ops[4] = { CastToType(Instruction::BitCast,

Please apply the attached (small) patch on top of it in the gcc directory. Worth noting, this front-end only works

hi, i also have problems compiling llvm-gcc (current svn version). llvm is current llvm svn. i tried to use every gcc version from 4.0 to 4.3 to compile llvm-gcc. i configured llvm-gcc like this (and tried every other combination of disable-shared, disable-multilib and bootstrap) : ../llvm-gcc/configure --prefix=/usr --enable-llvm=/usr --enable-languages=c,c++ --disable-shared

There are various functions in llvm-convert.cpp that depend on BITS_BIG_ENDIAN: TreeToLLVM::EmitLoadOfLValue() TreeToLLVM::EmitMODIFY_EXPR() InsertBitFieldValue() ProcessBitFieldInitialization() The comments say things like: // If this target has bitfields laid out in big-endian order, invert the bit // in the word if needed. // If this is a big-endian bit-field, take the top

I am trying to build llvm-gcc4 on a amd64. I had to add the attached patch to get the build system to select the correct library. Now the build fails while compiling a code that has __builtin_va_copy. The attached test.i fails with: cc1: ../../trunk/gcc/llvm-convert.cpp:443: llvm::Value* TreeToLLVM::Emit(tree_node*, llvm::Value*): Assertion `(isAggregateType(((exp)->common.type)) == (DestLoc

I've built a debug build of llvm 2.6, and llvm-gcc 2.6 for arm-elf with --enable-checking=yes. On the attached test case (which is g++.dg/expr/bitfield4.C from the GCC 4.2 testsuite) I get: $ cc1plus bitfield4.ii -emit-llvm-bc -o bitfield4.o -quiet cc1plus: /home/foad/svn/antix/toolchain/branches/w/foad/2757llvm26/toolchain/llvm/llvm-gcc/gcc/llvm-convert.cpp:999: llvm::Value*

See the bug for a reduction and the gimple trees. validate_arglist definately is rejecting the arglist in EmitBuiltinAlloca.

I meant: compile some nested C++ with llvm-gcc to see what it does.

Hi, in order to get a handle on the questions in Chris's previous email, I rebuilt LLVM with debugging info, and then rebuilt gcc4 with CHECKING_ENABLED. In the process, I ran into an assertion error when compiling the first part of libgfortran: ../../src/gcc/llvm-convert.cpp:3871: failed assertion `(TREE_CONSTANT(exp) || TREE_CODE(exp) == STRING_CST) && "Isn't a

On alpha, I am seeing a problem with Emiting va_copy.  valists are structs and allocated by alloca, unlike x86.  EmitBuiltinVACopy is therefore using the second branch of the if (~llvm-convert.cpp:6538) to emit the second argument.  The second argument is the result of an alloca.  TreeToLLVM::Emit is hitting the first assertion (~929). The exp being passed is:  <var_decl 0x20000b44240 ap
