similar to: [LLVMdev] Failure to compile llvm-gcc-4.2-2.7 on FreeBSD on sparc machine

The patch is incorrect and the problems you're seeing are caused by your patch, since sparc != sparc64. In LLVM sense "sparc" means "sparc with ILP32 architecture

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  

Hi Chandler, > void > foo () { > float x __attribute__ ((mode (XF))); > } nice reduction. I don't see any problem on x86-32, and I don't have access to an x86-64 box right now. Can you please open a PR for this, and also run in the debugger. When you hit the abort, use "up" to go up a stack frame or two or three, and print out the gcc types [use: call

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

Also, does -fplugin-arg-dragonegg-enable-gcc-optzns get Dragonegg to match GCC performance where GCC was faster? Marcus

I am getting an assertion firing while building TOT llvm-gcc on Cygwin in libgcc2.c :- /home/ang/build/llvm-gcc/./gcc/xgcc -B/home/ang/build/llvm-gcc/./gcc/ -B/home/an g/llvm-gcc/i686-pc-cygwin/bin/ -B/home/ang/llvm-gcc/i686-pc-cygwin/lib/ -isystem /home/ang/llvm-gcc/i686-pc-cygwin/include -isystem /home/ang/llvm-gcc/i686-pc-c ygwin/sys-include -O2

Ah, hell, as soon as I've send this email I've updated from CVS to find that

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

Bam. This is about as reduced as it gets. I think I can spot the problem point: chandlerc at osiris ~/code/compilers/build/llvm-gcc $ cat testcase.i void foo () { float x __attribute__ ((mode (XF))); } chandlerc at osiris ~/code/compilers/build/llvm-gcc $ ./gcc/cc1 -fpreprocessed -march=k8 testcase.i -o /dev/null foocc1: /home/chandlerc/code/compilers/llvm-gcc/gcc/llvm-types.cpp:81: const

The NIST F77 test suite doesn't seem to be compatible with gfortran at all, so I had to work from my own sample codes, and generate test cases from them. Here's what works now, and I have a separate test case for each of these: statement functions intrinsic functions (print, cos, etc) loops, goto statments scalarized array operations function calls with *no arguments* simple common

With the patch from Chris and then the patch from you combined, the previous error disappeared, but I get another error, reduced to this: ./cc1 -fpreprocessed libgcc2.i -quiet -dumpbase libgcc2.c -mtune=pentiumpro -auxbase-strip libgcc/./_clz.o -g -O2

See the bug for a reduction and the gimple trees. validate_arglist definately is rejecting the arglist in EmitBuiltinAlloca. (try: bool TreeToLLVM::EmitBuiltinAlloca(tree exp, Value *&Result) { tree arglist = TREE_OPERAND(exp, 1); if (!validate_arglist(arglist, INTEGER_TYPE, VOID_TYPE)) { debug_tree(arglist); return false; } Value *Amt = Emit(TREE_VALUE(arglist), 0); Amt =
