From: Andrew Stubbs Date: Thu, 17 Jan 2019 12:34:28 +0000 (+0000) Subject: GCN back-end config X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7431c1a19641953d1d941b346b496c41711c9f0e;p=gcc.git GCN back-end config This patch contains the configuration adjustments needed to enable the GCN back-end. The new configure check for dlopen is required to allow building the new gcn-run tool. This tool uses libdl to load the HSA runtime libraries, which are required to run programs on the GPU. The tool is disabled if libdl is not available. 2019-01-17 Andrew Stubbs Kwok Cheung Yeung Julian Brown Tom de Vries Jan Hubicka Martin Jambor * configure.ac: Likewise. * configure: Regenerate. * contrib/config-list.mk: Add amdgcn-amdhsa. gcc/ * config.gcc: Add amdgcn*-*-amdhsa configuration. * configure.ac: Check for dlopen. * configure: Regenerate.
