similar to: A query language for LLVM IR (XPath)

As much as I'm not a fan of most XML things, this application of XPath is *inspired*. This would be a great testing/query tool for tests. It would also be a great way to prototype passes. Looking forward to seeing something like this in llvm/tools/ ! Cheers > On 1 Nov 2017, at 04:00, Sean Silva via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > This is so cool! I once

Hi, I wrote yet another [1,2] Python binding for LLVM! I'm doing this because llvmlite has some serious limitations: 1) it cannot parse an existing IR, only create new modules [3], 2) it keeps its own representation of the IR (which is less memory efficient than the LLVM one), and 3) each llvmlite version supports a single LLVM version. Considering that my need is to load modules of hundreds

There is llvmlite http://llvmlite.readthedocs.io/en/latest/ , but it doesn't seem to support reading individual instructions, based on these docs. I was thinking to make a simple code analysis tool to, for example, find all system calls that have unchecked return codes, but I can't find a binding for any scripting language. And I am averse to writing this in C++. Thanks, Yuri

hi , i cant succeed add variable in xpath (libxml) brand = "037" xpath = "//Root/Stk[@Category=''601'' and @Brand=#{brand}]" stack = node.find(xpath) i used #{brand} but doesnt work

Hi, I'm getting: Unhandled exception at 0x00C211F0 in ConsoleApplication830.exe: 0xC00001A5: An invalid exception handler routine has been detected (parameters: 0x00000001). With some fairly simple SEH enabled routine: define i32 @__elements_entry_point_main(%._gt2a_RemObjects_d_Elements_d_System_d_Array_t_1s*) #0 personality i8* bitcast (i32 ()* @_elements_exception_handler to i8*) !dbg

Indeed, it's 32bits x86 and there's no .safeseh or anything like it, even readobj -coff-load-config says nothing: File: ConsoleApplication830.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit Now I know what to look for, thanks!

'virt-inspector --xpath' can segfault. When run under valgrind, it shows this error: ==2254== Invalid free() / delete / delete[] / realloc() ==2254== at 0x4C29D6A: free (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==2254== by 0x53BA198: xmlFreeNodeList (tree.c:3690) ==2254== by 0x53B9F65: xmlFreeDoc (tree.c:1247) ==2254== by 0x405BFA: do_xpath (inspector.c:808)

What built in utilities are there that can evaluate XML XPath statements in CentOS? Its needed to grab certain info from <a href="some.html">some</a> from a page with a python, perl or shell script. Hints on what to use would be appreciated. Chris -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I'm looking for help extracting some information of the zillow website. I'd like to do this for the general case where I manually change the address by modifying the url (see code below). With the url containing the address, I'd like to be able to extract the same information each time. The specific information I'd like to be able to extract includes the homedetails url, price

Dear R experts, I try to extract certain child nodes from an XML document and construct a table in which the parent node names are the columns and the child id values, joined in a list, are the cell content. If I first apply an XPath query to extract all above parent nodes, then iterate over those nodes and again apply a XPath query to select their child nodes, I get *ALL* matching child nodes

We got all rows by: library(XML) doc = htmlParse('http://www.statcan.gc.ca/daily-quotidien/090520/t090520b1-eng.htm') rows = xpathSApply(doc, '//table/tbody/tr') The last row is: row_last = rows[15] row_last [[1]] <tr><td id="t1stub17" class="stub1 RGBShade"><b>Unsmoothed composite leading indicator</b></td>&#13; <td
