similar to: [LLVMdev] Minor FileCheck proposal: CHECK-UNIQUE for labels to improve error messages

Hi, I would like to add a new directive to FileCheck called CHECK-FOO (where FOO is a name under discussion right now) which is used to improve error messages. The idea is that you would use CHECK-FOO on any line that contains a unique identifier (typically labels, function definitions, etc.) that is guaranteed to only occur once in the file; FileCheck will then conceptually break the break the

Hi Rafael, I think you saw my other e-mail, but just in case you haven't, do you have any thoughts about making this an option that could be easily disabled on the command line without maintaing a patch to lit? I think it would help out-of-tree target maintainers to transition, since I'm sure there will be a lot of similarly broken tests to fix. Stephen On Thu, Jul 4, 2013 at 8:56 PM,

Hi all, By default, FileCheck will emit an error if you try to get it to check an empty file. This doesn't seem like a bad idea to me, since it might protect against certain unintended usages. However, in every use-case I know of, it's also combined with checks that essentially say "don't just allow the output to be empty, fail if it isn't". In some cases, those checks

We currently don't use pipefail when running test under make check. This has the undesirable property that it is really easy for tests to bitrot. For example, something like llc %s | FileCheck %s will still pass if llc crashes after printing what FileCheck was looking for. It is also easy to break the tests when refactoring. I have fixed tests that were doing %clang_cc1 -a-driver-options

Hi, I'm not planning on doing this, but I noticed that the documentation in WritingAnLLVMPass.rst doesn't seem to specify whether or not it's legal for a function pass to inspect (and thus depend upon the contents of) other functions and I'm curious if this is an oversight or by design: To be explicit, ``FunctionPass`` subclasses are not allowed to: #. Modify a

Greetings all, I'm porting an algorithm from MATLAB to R, and noticed some minor discrepancies in small decimal values using rowSums and colSums which are exacerbated after heavy iteration and log space transformation. This was rather perplexing as both programs claimed and appeared to use the IEEE 754 standard for floating point arithmetic (confirmed with manual basic operations).

Hi all, Are there any plans for better documentation for the new StoryRunner feature? I tried to use it today (with Rails), and had a hard time getting my head around whether I was doing it "right" and exactly what things are appropriate to test at that level (this might be exacerbated by the fact that I''ve never really used integration testing that much). A full example of

Hi there, I'm new to this list, and in fact rather new to the Ogg/Vorbis codec altogether. I recently downloaded the test files from the test conducted by the German computer magazine c't (this was mentioned by someone here recently). The idea was that you were given seven WAV files each for 64kbps and 128kbps, and had to rate them. The files were randomly chosen for each participant.

Hi R forum, Each row of my data (below) show a new contact event between animals. In order to ultimately look at the patterns of intervals between contacts, I need to calculate a contact end time.

I am trying to re-organizing my Makefile for testing my R packages and I am having trouble finding a structure I like. The problem seems to be that "R CMD check", which does wonderful things, does not allow dependency information to flow through very gracefully. That is, since everything is copied into the pkg.Rcheck directory, it is difficult to make any changes to source files without

Hi Rsync/Samba team, First of all, cudos on rsync 2.6.6! It is running exceptionally well. I'm using a script executed by cron to keep warm-backup servers in sync with the primary server. The execution is set to run every 5 minutes. Like any good programmer, this process is *very* paranoid and uses 'wall' to notify the users if any error occurs during the transmissions. This is

Dear R help I have conducted a fa() analysis, and I want to use fa.diagram to assess the extent to which the 11 latent factors predict the 37 items in a psychological battery. However, the display on the screen has very large font size for the coefficients of the relationship between the 11 factors and the 37 items, so the numbers overlap and are therefore illegible. When I output this to a
