Profraw files

In my home directory i have profraw files (default_942482837171841843_0.profraw). If i delete them, they reappear. What are profraw files? Can i chanege their destination folder or delete them permanently?

It seems to be something related to the clang compiler.
If interested (I'm not a developer, just found it with a quick search :wink:) read e g.:
https://clang.llvm.org/docs/UsersManual.html
Could be here:

Run the instrumented executable with inputs that reflect the typical usage. By default, the profile data will be written to a default.profraw file in the current directory. You can override that default by using option -fprofile-instr-generate= or by setting the LLVM_PROFILE_FILE environment variable to specify an alternate file. If non-default file name is specified by both the environment variable and the command line option, the environment variable takes precedence. The file name pattern specified can include different modifiers: %p, %h, and %m.

facing the same issue , i deleted these file but as soon as i opened firedragon the profraw files got regenerated.

Me too after boot and starting firedragon. This is the largest I found:
.rw-r--r-- 49M arthur 11 May 13:01 ๏…› default_12781971547894223488_0.profraw

Anyway they keep coming back.

Yes,The profraws started after I tried to build Unreal. The build crashed before finishing. That was an oh well. Maybe later.

I build nothing and saw this files first time.

I'm getting this too and did the research. However I'm clueless about this atm. Since it also happens with Librewolf, I created an issue at their Gitlab. Maybe they have some insight.

I confirm this, both on physical machines and VMs, not using LLVM.

Firedragon v99 works fine, but somewhere between 99.0 and 100.0 it started.

Dragon, could you post the link to the gitlab, plz?
Ah nevermind, it's clear to me it's this one .profraw files getting generated on browser exit (#84) ยท Issues ยท LibreWolf / Browser / Arch ยท GitLab
