Multiple key presses are hindered when repeat turned off
I have verified this on two machines, but it would be helpful if others
out there can reproduce it too. Also, I do not know if it is Xorg or
the FreeBSD keyboard drivers, since I see no way to reproduce on the
console (i.e. turn off repeat).
In an xterm, type: "xset r off". Then try some multiple-key
combinations (i.e. keep holding first key(s) when you type the next one):

Optimizations hindered by GVN widening
Currently, the GVN optimization widens loads if the alignment permits it. There are some limitations that show up, as seen in example below:
Initial IR:
declare void @consume(i8) readonly
define i8 @bar(i8* align 2 %a) {
%1 = load i8, i8* %a
%idx = getelementptr i8, i8* %a, i64 1
%2 = load i8, i8* %idx, align 1
call void @consume(i8 %1).
ret i8 %2
}
define i1 @foo(i8* %a) {

Quotation marks hinder for loop
Dear mailing list members,
My question is maybe very basic, but I could not find the solution.
I would like to do the following things
1)
colnames(V1)[2] <- par$V2[1]
colnames(V2)[2] <- par$V2[2]
colnames(V3)[2] <- par$V2[3]
...
colnames(V37)[2] <- par$V2[37]
2)
V1 <- V1[,-1]
V2 <- V2[,-1]
V3 <- V3[,-1]
...
V37 <- V37[,-1]
3)
ms <- merge(V1,V2)
ms <- merge(ms,V3)

The lone PC in Raleigh
Last week I had the pleasure of attending the Raleigh area Ruby users Meetup.
It was very interesting and very informative.
I did feel a bit out of place when we noticed that of the 11-12 people
there, I was the only one with a PC laptop. The rest were shiny macs.
Ah well, I need to replace this thing soon, and now that BootCamp is
out, I really have no more excuses. This way I can test

Code in headers
While investigating compile times, I noticed that there's no information in
the LLVM coding standards about code in headers. Many LLVM/Clang headers
have lots of complex code in headers - I'm specifically looking at the
Static Analyzer projects (seemingly slowest compile times, biggest
hinderance to my productivity) - that probably doesn't need to be there.
Nobody likes slow compile times.
What's the LLVM policy on code in headers?
If there is none, the Chromium "C++ Dos and Don'ts"

Using Winamp for ogg streams/files
hello,
It appears that Winamp 3 has problems playing ogg streams/files. I can't
say exactly since I don't use Windows myself. I tried the very alpha
Winamp for Linux and it was quite useless.

Reading data with blank elements
Hi,
I have a dataset saved in *.csv format, that contains
13 columns (the first column being the title name and
the rest experiments) and about 2500 rows.
Not all columns in the row have data in it

Loop optimization
Hi,
I was wondering if there is an optimization pass in LLVM or Polly that can optimize this given loop:
int main(int argc, char* argv[]) {
char s = 0;
// Loop is setting s = argv[1][0];
for (int i=0; i<argv[1][0]; i++) {
s++;
}
printf("s = %c\n", s);
return 0;
}

[RFC] Use of saturating intrinsics
Hello all again, take 2.
Over in D68651 I would like to make code that attempt to saturate an value (using higher bitwidth integers) use a saturating intrinsic instead. Something like this:
https://godbolt.org/z/9knBnP
As can be seen, the unsigned cases are already being matched to llvm.uadd.sat intrinsics. I am hoping to extend that to the signed cases. This has numerous benefits including

GPLPV drivers suspected to hinder live migration to different CPU type
Hi,
I''ve noticed that on a Xen cluster with three nodes (two E5620 CPUs and
one E5140 CPU) live migration works perfectly in between to two E5620
nodes, but fails to and from the E5140. The error message is about a HVM
context not being able to be set.
I strongly suspect the use 238 GPPVL drivers, but I cannot uninstall
them at this point because someone else needs the server.

How to stop mail_executable from cwd to ~home
In our environment home directories are auto-mounted via /home/<user>
including on the server provided mail.
Within the various mail services though we try to isolate
and override with local /mail/home/<user>
Works well except that dovecot still wants to cd to the real home
triggering a useless and potentially hindering automount
when it invokes the imap or pop3 process specified by

InstCombine GEP
Hi,
I have a doubt with GEP transformation in the instruction-combiner.
Consider below test-case:
struct ABC {
int A;
int B[100];
struct XYZ {
int X;
int Y[100];
} OBJ;
};
void Setup(struct ABC *);
int foo(int offset) {
struct ABC *Ptr = malloc(sizeof(struct ABC));
Setup(Ptr);
return Ptr->OBJ.X + Ptr->OBJ.Y[33];
}
Generated IR for the test-case:
define i32 @foo(i32
