|
||||||
Subject: pahole: Fix discarded-qualifiers for strchr/strstr.
|
|
||||||
|
|
||||||
Glibc 2.43 added C23 const-preserving overloads :
|
|
||||||
https://sourceware.org/glibc/wiki/Release/2.43.
|
|
||||||
|
|
||||||
For the function prototype__new, fix local variable declaration to use
|
|
||||||
the correct const char* type instead of char*, removing the need to
|
|
||||||
discard the const qualifier.
|
|
||||||
|
|
||||||
Also fix a pre-existing bug in type__find_type_enum: when iterating
|
|
||||||
over a '+'-concatenated list of enum names, after advancing to the next
|
|
||||||
segment the new separator was not nullified, causing "second+third" to
|
|
||||||
be passed to cu__find_enumeration_by_name instead of "second". Add a
|
|
||||||
null check before writing to sep_mutable to avoid a null dereference
|
|
||||||
when no further '+' is present.
