Subject: [PATCH] find-debuginfo.sh: Filter out all <built-in> like fake file
|
|
names.
|
|
|
|
There is no official way to mark an instruction range as being not
|
|
part of some actual source code, but as part of a compiler built-in
|
|
construct in DWARF. So different compilers have come up with fake
|
|
source file names like <built-in> or <__thread_local_inner macros>.
|
|
We already filtered out the strings "<internal>" and "<built-in>".
|
|
Just filter out all '(^|/)<[a-z _-]+>$'. They are fake files!
|
|
|
|
This is mainly to appease the rustc compiler which generates lots of
|
|
different variants to encode some instruction sequence is part of an
|
|
compiler generated macro expansion.
|
|
