Hi! When I go to http://llvm.cs.uiuc.edu/doxygen/annotated.html and click on link for, say, "llvm::Module", I've told that the target page does not exist. Same happens for llvm::Value, and in fact everything under "llvm" namespace. Any idea what's wrong? - Volodya

Hello, I'm playing with alias analysis, using the following program: %i = external global int ; <int*> [#uses=2] implementation ; Functions: int %_Z3bari(int %p) { entry: %tmp.0 = load int* %i ; <int> [#uses=1] %tmp.1 = setgt int %tmp.0, 10 ; <bool> [#uses=1] br bool %tmp.1, label %then, label %UnifiedReturnBlock then:

The gcc4 tree is in svn. We believe it should be straight forward to create a public svn image but it will be late next week before we can set it up (minimal svn experience between Chris and myself.)

On my target, the multiplication can involve all general purpose registers, but there's are still some restrictions: the first and the second operand as well as the result must be in different registers, and neither register can be gr7. How can I enforce this restriction on the register allocator? - Volodya

Hello, I've just tries make && make install on a fresh CVS tree, and get: llvm[0]: Installing include files /bin/sh: line 1: pax: command not found Two questions. 1. Why install process requires some nonstandard tool? Is it possible to get away without it. 2. autoconf/configure.ac has this: AC_PATH_PROG(PAX, [pax], [pax]) but Makefile.rules uses plain 'pax',

I've another problem. There's one register, gr6, which is used to return high part of return value for functions returning 64-bit values. For such functions, the register should not be saved, naturally. But when function does not return 64-bit value, then the register must be saved. How can I express this in .td file? - Volodya

The above-mentioned test contains this: long B53 = - (1LL << 53); strictly speaking, this is not correct code. The C standard says about shift: "if the value of the first operator is ... or greater than ... the width of the promoted left operand, the behaviour is underfined". Thouhts? - Volodya

Hello, after some time I'm trying to build my code with the current CVS of LLVM, and have a problem. The mentioned file, around line 184, contains: if (FixedSlot == FixedSpillSlots+NumFixedSpillSlots) { // Nope, just spill it anywhere convenient. FrameIdx = FFI->CreateStackObject(RegInfo->getSpillSize(Reg)/8,
