From dbb024cf94e6a7603ac0484be3c44d2f29eeceb6 Mon Sep 17 00:00:00 2001 From: Sergey Dmitriev Date: Fri, 27 Sep 2019 20:00:51 +0000 Subject: [PATCH] [Clang][OpenMP Offload] Create start/end symbols for the offloading entry table with a help of a linker Linker automatically provides __start_
and __stop_
symbols to satisfy unresolved references if
is representable as a C identifier (see https://sourceware.org/binutils/docs/ld/Input-Section-Example.html for details). These symbols indicate the start address and end address of the output section respectively. Therefore, renaming OpenMP offload entries section name from ".omp.offloading_entries" to "omp_offloading_entries" to use this feature. This is the first part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943).
