When is PATH directive used?
...le config entry
to load the correct memdisk depending on current running architecture.
If I specify the relative path to the binary, then my config is specific
to an architecture. If there were some kind of support to set a custom
variable, then I could at least do this:
archstub.cfg:
SET MYARCH=bios
INCLUDE rest.cfg
rest.cfg:
...
LINUX syslinux/$MYARCH/memdisk
At any rate, my impression at this point is that "common directory
distinct config" is not workable, when it seemed initially like an
attractive way to have most of the config (all but an initial stub to

[LLVMdev] Type inference on registers with can contain multiple types
My architecture has an FPU, but uses integer registers to store
floating-point values. So each register can store either an int or an
IEEE float. I define a register class like this:
def GR32 : RegisterClass<"MyArch", [i32, f32], 32,
(sequence "R%u", 0, 32)>;
So far so good. However, when I write a rule to store a register:
def STORE32r : S32<
(outs), (ins GR32:$rS, GR32:$rD),
"st {$rS, ($rD)}",
[(store GR32:$rS, (iPTR GR32:$rD))]>;
...then I get the dreaded 'cannot...

yum does not update x86_64

if re.search('alpha', arch):
newarch = 'alpha'
if re.search('ppc', arch):

if not newarch:

When I run it, it returns 'x86_64':

What can be wrong ?
Thanks for your help.

How to get CLang array alloca alignments to be smaller than 16 bytes?
I am working on a custom LLVM backend for a 16 bit architecture.
For my architecture, I need smaller array alignments for arrays created on the stack.
For example, consider the following code at the start of a C function:
char localBuff[20];
char localBuff2[6];
this gets converted by Clang into this:
%localBuff = alloca [20 x i8], align 16
%localBuff2 = alloca [6 x i8], align 1

[LLVMdev] Cross compiler
Dear All,
I am a newcommer. Terribly sorry for the basic questions whose answers may be out there somewhere.
My questions are the followings:
-With the front end clang, what can be the possible values for the -target parameter? Can I have a full list of them?
-How can I create a (static) library from the object files as with the command "ar" in linux ? I wonder whether I should use

IBM BladeCenter HS20 blades
Greetings,
We have purchased an IBM BladeCenter and I am in the process of testing
Linux installation on these things (boot off SAN i.e. qla2300 driver,
not using internal drives). My distro of choice is Debian, however,
since I'm really not interested in trying to hand compile all the
drivers, I decided to try CentOS (which I'm so far very impressed with).
On boot, as with the
