From 4fb4e7e821e36180835bf88e363f9f13b5797e3a Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Sun, 5 Dec 2021 13:50:17 +0100 Subject: csu: Always use __executable_start in gmon-start.c Current binutils defines __executable_start as the lowest text address, so using the entry point address as a fallback is no longer necessary. As a result, overriding is only necessary if the entry point is not called _start. The previous approach to define __ASSEMBLY__ to suppress the declaration breaks if headers included by are not compatible with __ASSEMBLY__. This happens with rseq integration because it is necessary to include kernel headers in more places. Reviewed-by: H.J.
