Full_Name: Eric van Gyzen Version: 2.1.0 OS: FreeBSD 5.4 Submission from: (NULL) (152.3.22.33) R-2.1.0 fails to compile on the newest release of FreeBSD, complaining about undefined references to __builtin_alloca. On FreeBSD, alloca() is declared in stdlib.h, not alloca.h as the R sources expect. Therefore, HAVE_DECL_ALLOCA does not get set, so the R sources declare alloca() after it has already been #defined by stdlib.h. A possible fix is to modify the configure script to look for the declaration of all...

This whole path is only triggered when the compiler is unable to use C99 var arrays. Did you actually bump into this with something that can use configure? (e.g. do we have a problem with the var array test someplace)

PR1711 is an x86 codegen problem that is blocking adoption of llvm-gcc by people using linux on x86-64 boxes. Could someone with access to one of these boxes take a look? I'll help try to debug this, but I don't have access to a machine. I bet it's a small tweak required in the x86 backend. Thanks! -Chris

I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to
