[PATCH 0/2 v3] mkstemp() and m68k support
Hi,
after a year, I decided to hack on klibc again. I?ve reworked
both the patch to add mkstemp(), discussing to use AT_RANDOM
as cheap entropy source on IRC (if there will ever be another
entropy consumer, I can quickly write a minimal arc4random()
seeded from it, as it has only 16 octets), capable of making
a working mksh (static and shared) on amd64/xen, and the m68k
support code, leading to

[klibc 00/31] klibc as a historyless patchset (updated and reorganized)
I have updated the klibc patchset based on feedback received. In
particular, the patchset has been reorganized so as not to break
git-bisect.
Additionally, this updates the patch base to 2.6.17-git12
(d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main
difference on the klibc side is removal of obsolete code.

[LLVMdev] Universal tool for creating your own language and parsing the AST
Hi everyone,
I'm writing a language, that will be a "generic language", useful for (I hope) describing any language.
It's called Jeebox.
I've had success describing C, ObjC, PHP, JavaScript, Java, my own language SpeedyCog, and others.
It isn't released YET... but I am working on it.
What is the relevance to LLVM? Well... once Jeebox is released... it will remove one
