3Subject: Check incompatible existing default symbol definition
4X-Git-Tag: hjl/linux/release/2.24.51.0.3~1^2~8^2~16
5X-Git-Url: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff_plain;h=4584ec12076e088cf36965b88ef8710ca85491f9

7Check incompatible existing default symbol definition
8
9After resolving a versioned reference, foo@VER1, to a default versioned
10definition, foo@@VER1, from a shared object, we also merge it with
11the existing regular default symbol definition, foo. When foo is IFUNC
12and foo@@VER1 aren't, we will merge 2 incompatible definitions. This
13patch avoids merging foo@@VER1 definition with foo definition if
14one is IFUNC and the other isn't.

7Don't check shared/export_dynamic/ref_dynamic for type mismatch

9There is nothing linker can do when a type mismatched default definition
10are made dynamic by info->shared, info->export_dynamic or h->ref_dynamic.
11But we do want to avoid exporting it when building PIE. Let's remove
12those checks.
