From d6afa561e1471ccfdaf7191230c0c59a37e45a5b Mon Sep 17 00:00:00 2001 From: David Miller Date: Wed, 17 Oct 2018 12:08:59 -0700 Subject: perf symbols: Set PLT entry/header sizes properly on Sparc Using the sh_entsize for both values isn't correct. It happens to be correct on x86... For both 32-bit and 64-bit sparc, there are four PLT entries in the PLT section. Signed-off-by: David S.
