Are you asking what the parsing rules are, or how you should modify the LLVM code to achieve that result? If the latter, you haven’t really given enough detail here. What code, exactly, have you tried modifying? Do you have any ideas for how it could work? -Eli From: Eric Astor <epastor at google.com> Sent: Tuesday, January 21, 2020 2:44 PM To: Eli Friedman <efriedma at

Hi Guys, I'm fairly new to Linux and I'm trying to un install a hard drive from my Centos 5.1 box running KDE. When I built the PC, I installed two 500 gig maxtors in the tower, then I installed Centos. Now I've decided that I want to remove the slave drive and use it as an external backup drive - I am mounting it into one of those external drive cases with a built in fan. When I

Hi, I?m trying to set up a private family web site for genealogy, and want to set up Apache Authorization access control for this site, and once the user has logged in has access to the entire site. I?ve been reading the info at http://httpd.apache.org/docs/2.2/howto/auth.html to learn how to do this. I?m just planning on passing out the same username and password to all family members and

Apologies - I apparently remembered part of the issue incorrectly, so this ended up quite confusing. The problem comes when referencing labels in a different section of the binary. To clarify, if I assemble the code: .data foo BYTE 5 .code mov eax, foo with Microsoft's ml64.exe, it emits an object file disassembling to: 0: 8b 05 00 00 00 00 mov eax, dword ptr [rip]

Agreed, I won't plan to change syntax for anything that hasn't opted in. However... Am I mistaken in thinking clang-cl (for example) is just clang with a different name, which triggers some variant behaviors including parsing cl.exe-style command lines and taking certain flags as implicit? I was hoping to build llvm-ml similarly, by building the features into llvm-mc behind target

Björn, Can you try adding -fno-integrated-cc1 to the command-line, see if you get more infos?

Hi, I'm trying to password protect one of my web accessable directories and I can't get .htaccess to work in a Centos 5.1 box Here's what I did I created an .htaccess file with the contents: AuthName "Restricted Area" AuthType Basic AuthUserFile /home/mysite/.htpasswd AuthGroupFile /dev/null require valid-user and I uploaded it to the dir I want to protect. Then I

Hi all, I'm trying to land (a rebased version of) http://llvm.org/D37461 - which should make it possible to handle x86 Intel assembly like mov eax, offset Foo::ptr + 1 (Currently, omitting the +1 works... but offset doesn't work in compound expressions.) I'm having trouble figuring out what inline assembly I can emit into the LLVM IR that will work properly. So far, the closest

Interesting - the patch doesn't address this yet. It looks like we have a difference (maybe bug?) in how we handle Intel vs. AT&T inline assembly: https://godbolt.org/z/GQw9ED Suppose we're expanding an operand with an 'i' constraint, where the operand is given as, e.g. (i32* @Bar). If the inline assembly is in Intel dialect, this expands as "Bar" in AT&T syntax

Hi all, While working on alias support for the LLVM-ML project, I ran into a feature implemented back in 2010: default-null weak externals in COFF, a GNU extension. https://reviews.llvm.org/rG17990d56907b I'd like to disable this feature when targeting MSVC compatibility. Does anyone have more context on this, and why it'd be a terrible idea? For context: This seems to be designed to let

I recently subscribed and saw in the archive that Eric Astor was asking for a formal grammar (unlikely the first time for such request.) Currently there are a few problems in making such a thing so I was curious if Mr. Gruber has made any thoughts about moving toward one? This would also allow a more ?clean? parser which would get rid of some of the current problems (bad nesting[^1],

Hi all, I'm working on a project that uses clang-cl & lld-link to build for Windows, along with some tools out of the Windows SDK... but we're currently pre-building some pieces of MASM assembly code using Microsoft's ml.exe & ml64.exe. Unfortunately, it's not all inline assembly, which clang can already handle, and Microsoft's file-level directives are a bit unusual.

Hi all, Continuing work on llvm-ml (a MASM assembler)... and my latest obstacle is in enabling MASM's convention that (unless specified) all memory location references should be RIP-relative. Without it, we emit the wrong instructions for "call", "jmp", etc., and anything we build fails at the linking stage. My best attempt at this so far is a small patch to

How would I setup dovecot so that when messages are moved to the Archive mailbox, they are marked as read? Would it be similar to the imap-sieve for spam tagging? imapsieve_mailbox1_name = Junk imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve Or is there a simpler method? If it matters: mailbox Archive { auto = subscribe

hello, maybe this is the wrong place, but according to http://us1.samba.org/samba/Linux_CIFS_client.html linux kernel cifs should be able to handle M$ dfs shares. I looked at the installation and usage instructions but it doesn't work. On the mount.cifs manpage I found no hint about a special switch to activate dfs parsing. Can anybody put some light into this? TIA -- Peter # uname
