mktemp foo.XX works here but perl's File::Temp is not working when I tried to build editors/openoffice.org-3-devel, I got: Error in tempdir() using /tmp/XX: Tried to get a new temp name different to the previous value 50 times.

Hi Roman,
I needed to build ldexp.{o,po,So} manually with -O2, and built every
other object using -O0, the same problem happened.

Hi,
As of r212979, you should now be able to build world and kernel on i386
and amd64 with clang, without any additional patches!
To do so, make sure you have updated your installed world to at least
r212904 (which has the most recently imported clang/llvm snapshot), and
put the following in /etc/src.conf:
.if !defined(CC) || ${CC} == cc
CC=clang
.endif
.if !defined(CXX) || ${CXX} == c++
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
Both world and kernel can also be installed, and should run properly,
but please make sure you have a way to revert if anything unexpected
happens. :) Alternatively, just install into a chroot to try it out
from there.

Thanks to all the people that made this possible, especially Roman
Divacky, Ed Schouten, Rui Paulo, and of course the clang/llvm
developers.
I built my desktop world + kernel with clang, rev. 213247 amd64, it
booted perfectly, the only problem i got was something went wrong
with a perl module File::Temp.
To be sure it's related i'm rebuilding the src (same rev.) with gcc and
will take a look if it will back to work. I'll send an email after testing.
Just to show, the problem i got with perl was using this code:
#!/usr/bin/perl
use File::Temp;
my ( $fh, $filename ) = File::Temp::tempfile();
print $filename\n;
unlink $filename;
with this results:
Error in tempfile() using /tmp/XX: Tried to get a new temp
name different to the previous value 50 times.
Something wrong with template?? (/tmp/XX) at testes/tmp.pl line 5

A test shell script using mktemp (1) works fine on current built with
clang today. The clang case produces a filename with all A's rather
than the random letters expected.
I didn't test mktemp, but my perl test code generate files
with all 'A' just after i reboot the machine with clang, after
few minutes it stop working and give the error I reported.
Please let me know if there is any kind of information I
can send to help fixing this.

Work is progressing steadily on the clang/llvm integrated assembler, which removes the need for an external assembler such as gas, and which should also reduce compile times further. This is really in alpha state right now, but Roman Divacky (who is one of the active contributors) can probably tell more about its progress. Another important component is of course the linker, but I am not aware of a similar project to replace that; excepting gold, but that is a GPLv3 project too, unfortunately. There has been another effort underway for some time: http://sourceforge.net/apps/trac/elftoolchain/ Perhaps some coordination between those working on llvm in FreeBSD, and the elftoolchain project, would be helpful? there's not that much overlap between those two - in a case elftoolchain gets to implementing linker it would be sweet if it supported the same plugin API as gold so we can use LLVM LTO plugin there... beside that I dont see much point in teaching nm to see into llvm object files etc. (we already have tools for that) ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Still the same without make.conf. My personal guess is, that clang builded by clang with CPUTYPE=athlon-xp is somehow broken. I don't think CFLAGS=-O2 -pipe could do any harm, and also note that clang builded by GCC with exactly the same make.conf has no problems with world building :) I still cannot reproduce your issue... To check, I have built world with CPUTYPE=athlon-xp, verified it used -O2 -pipe -march=athlon-xp as compilation flags for the world stage, and installed the resulting clang executables. Those clang executables do not exhibit the same problem as yours do; they can build tblgen (during the bootstrap-tools stage) fine. I suggest you comment out the CPUTYPE macro in make.conf for now, rebuild your world with gcc, and then rebuild it with clang again, to see if the issue goes away. Indeed, I was right. Problem is gone after hashing out CPUTYPE line, building world with GCC, and with clang after that. Now world is building without problems. But hey, i just realized that: # dmesg | grep -i cpu CPU: mobile AMD Athlon(tm) XP 2200+ (1800.11-MHz 686-class CPU) I simply forgot that about a year ago I changed Athlon XP in this BOX to Athlon MP and I didn't changed CPUTYPE in make.conf...

Available instructions and registers are identical between the two. Mobile variants of the Athlon XP should also be identical from a programming point of view. That's what I thought too, but in that case, why are they different optimisations available? In /usr/share/examples/etc/make.conf: # Currently the following CPU types are recognized: # Intel x86 architecture: # (AMD CPUs) opteron athlon64 athlon-mp athlon-xp athlon-4 # athlon-tbird athlon k8 k6-3 k6-2 k6 k5 Or maybe some of them are in fact bywords to compiler? Still, my CURRENT box is at idle mostly, so I will experiment a little and see what I get. Cheers Argh, I assumed that 'Mobile Athlon XP' == 'Athlon MP' while it seem's that they aren't. CPUTYPE=athlon-xp was a right choice for my CPU.

Hi,
As of r212979, you should now be able to build world and kernel on i386
and amd64 with clang, without any additional patches!
To do so, make sure you have updated your installed world to at least
r212904 (which has the most recently imported clang/llvm snapshot), and
put the following in /etc/src.conf:
.if !defined(CC) || ${CC} == cc
CC=clang
.endif
.if !defined(CXX) || ${CXX} == c++
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
Both world and kernel can also be installed, and should run properly,
but please make sure you have a way to revert if anything unexpected
happens. :) Alternatively, just install into a chroot to try it out
from there.
Some additional information can be found on this wiki page:
http://wiki.freebsd.org/BuildingFreeBSDWithClang
Thanks to all the people that made this possible, especially Roman
Divacky, Ed Schouten, Rui Paulo, and of course the clang/llvm
developers.

Still the same without make.conf. My personal guess is, that clang
builded by clang with CPUTYPE=athlon-xp is somehow broken. I don't think
CFLAGS=-O2 -pipe could do any harm, and also note that clang builded by
GCC with exactly the same make.conf has no problems with world building :)

Hi,
As of r212979, you should now be able to build world and kernel on i386
and amd64 with clang, without any additional patches!
To do so, make sure you have updated your installed world to at least
r212904 (which has the most recently imported clang/llvm snapshot), and
put the following in /etc/src.conf:
.if !defined(CC) || ${CC} == cc
CC=clang
.endif
.if !defined(CXX) || ${CXX} == c++
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
I've uploaded a typescript of make buildworld make buildkernel of
an 9.0-amd64
system running r212906 and building r212994 with the clang-in-HEAD:
ftp://rene-ladan.nl/pub/freebsd/bwk-clang-native.bz2
SIZE = 933354 bytes (uncompressed 36308187 bytes)
SHA256 = f97be8fb0d310ceb2e16dfc3919aeb68b57312431d7e879b6cce84b1cf8ba851
Now for the install phase, after some backups.
