similar to: [LLVMdev] 16-bit x86 status update

I just want to state that I hope we never implement the 16-bit Microsoft C++ ABI for -m16.

When experimenting with compiling GRUB2 with clang using integrated as, I found out that it generates a 16-bit code bigger than gas counterpart and result gets too big for size constraints of bootsector. This was traced mainly to 2 problems. 32-bit access to 16-bit addresses. source: movl LOCAL(kernel_sector), %ebx movl %ebx, 8(%si) clang: 7cbc: 67 66 8b 1d 5c 7c 00 addr32 mov 0x7c5c,%ebx

Hello, I am trying to compile RHEL-6 kernel srpm on Fedora 14 and run into the following problem. From what I read -Werror flag causes warnings to be treated as errors - but I don't see that flag on in the following. Any ideas? gcc -Wp,-MD,arch/x86/kernel/acpi/realmode/.wakemain.o.d -nostdinc -isystem /usr/lib/gcc/i686-redhat-linux/4.5.1/include -nostdinc -isystem

It appears that it's impossible to duplicate a node in the dag. For example, there is some code: b = a * a; // a is a global int A LD node is generated for A and it goes into both Operand 0 and 1 of the MUL node. The issue is I'm trying to match a pattern of: set dstReg:$dstD (OpNode (srcAType (load addr32:$srcA)), (srcBType (load addr32:$srcB))) so basically a mem, mem, reg

Hi all don''t get such envionment to try now. so ask for help here. imagine that two os installed. Xen3.1 + Linux is installed in /dev/hda and windows xp is installed in /dev/hdb I don''t want to reboot to use windows. Is it possiable to boot the hdb windows in xen? i saw there are some threads about P2V in this mail list. will the P2V tools help? thanks

Hi, I?ve strange problem when I?m making a call from SIP (Cisco 7960) to capi (Fritz PCI). When I call a national number, I?m hearing the ringtone when the called party is ringing but when I call an international number, I don?t hear the ringtone and I?ve a silence until the called party answers. Both call are going through the same extension. Here?s 2 log files, one with a national number and

This is a quick hack to experiment with parallel threading model in the python plugin. Changes: - Use aligned buffers to make it possible to use O_DIRECT. Using parallel I/O does not buy us much when using buffered I/O. pwrite() copies data to the page cache, and pread() reads data from the page cache. - Disable extents in the file plugin. This way we can compare it with the python

- Use driver level (0x2) for NV_DEBUG instead of all levels - Create a NV_DEBUG_KMS for KMS level (04) and use them in modesetting code - Remove a few odd NV_TRACE calls and replace with NV_DEBUG_KMS Signed-off-by: Maarten Maathuis <madman2003 at gmail.com> --- drivers/gpu/drm/nouveau/nouveau_bios.c | 12 +++++----- drivers/gpu/drm/nouveau/nouveau_connector.c | 8 +++---

Which BTQ? There are three flavors. BTQ reg/reg BTQ reg/mem BTQ reg/imm I can imagine that the reg/reg and especially the reg/mem versions would be slow. However the shrq/and versions *with the same operands* would be slow as well. There's even a compiler comment about the reg/mem version saying "this is for disassembly only". But I doubt BTQ reg/imm would be microcoded. -- Ite

Cheers Remko and Ralph. I think there was some mention in the lets encrypt FAQ that certbot doesn't do email. But I understand I can use their generated very for dovecot, postfix and https? That would be good indeed. Anyone know of any manual, or can I just replace the certs in the dovecot and postfix locations with theirs? Do dovecot, postfix and apache all support .pem format?

When we add -ffreestanding the compiler won't get to inline this any more.

Hello, I would like to read sets of files within a folder, perhaps using recursive methods. Right now, I rename the files before import. It would be even better to do this without renaming files, without providing explicit filenames, perhaps by importing files based on chronology, and translating each filename into a header? Please excuse my ignorance, and help cure my clunky programming

Thanks Ralph, i?ll look into that. I think let?s encrypt uses certbot though and it can?t do email certificates (although i?m sure i can convert the cert i get from let?s encrypt, i?ll look into it. > On 9 Aug 2017, at 16:40, Ralph Seichter <m16+dovecot at monksofcool.net> wrote: > > On 09.08.2017 17:20, Alef Veld wrote: > >> So i?m using dovecot, and i created a self
