+Subject: Check incompatible existing default symbol definition
+X-Git-Tag: hjl/linux/release/2.24.51.0.3~1^2~8^2~16
+X-Git-Url: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commitdiff_plain;h=4584ec12076e088cf36965b88ef8710ca85491f9
+
+Check incompatible existing default symbol definition
+
+After resolving a versioned reference, foo@VER1, to a default versioned
+definition, foo@@VER1, from a shared object, we also merge it with
+the existing regular default symbol definition, foo.  When foo is IFUNC
+and foo@@VER1 aren't, we will merge 2 incompatible definitions.  This
+patch avoids merging foo@@VER1 definition with foo definition if
+one is IFUNC and the other isn't.
+
+Upstream-Status: Backport
