From 14c3ec67236b2d90c553d2575950369aa6fa43c5 Mon Sep 17 00:00:00 2001 From: Jesse Taube Date: Tue, 9 Jul 2024 13:39:34 -0400 Subject: [PATCH] RISC-V: pi: Force hidden visibility for all symbol references Eliminate all GOT entries in the .pi section, by forcing hidden visibility for all symbol references, which informs the compiler that such references will be resolved at link time without the need for allocating GOT entries. Include linux/hidden.h in Makefile, like arm64, for the hidden visibility attribute.
