Description Gabriel Nava Marino 2021-10-18 18:38:36 PDT 
First try:
set-webkit-configuration --coverage --debug then make

These errors will occur during the GenerateTAPI step:
error: headers don't have symbol '(weak-def) ___llvm_profile_filename'
error: headers don't have symbol '(weak-def) ___llvm_profile_raw_version'
error: headers don't have symbol '(weak-def) _lprofDirMode'

These seem related to https://bugs.webkit.org/show_bug.cgi?id=226684. However, reverting the change results in another error mentioned in https://bugs.webkit.org/show_bug.cgi?id=226562.

I wonder if we can disable TAPI for Debug builds.  I'm not sure there's a need for it in those builds, unless developers only build Debug locally and would miss new issues they created.
