From: James Greenhalgh X-Patchwork-Id: 217549 Message-Id: <1359740555-10179-5-git-send-email-james.greenhalgh@arm.com> To: gcc-patches@gcc.gnu.org Cc: marcus.shawcroft@arm.com Date: Fri, 1 Feb 2013 17:42:33 +0000 Hi, emit_library_call takes an `enum library_type` as its second argument. Currently aarch64-4.7-branch passes it an int 0. This patch fixes this, mirroring trunk, by passing LCT_NORMAL instead. This patch fixes the warning: config/aarch64/aarch64.c: In function ‘aarch64_trampoline_init’: config/aarch64/aarch64.c:3893:8: warning: enum conversion when passing argument 2 of ‘emit_library_call’ is invalid in C++ [-Wc++-compat] Regression tested on aarch64-none-elf with no regressions. OK for aarch64-4.7-branch?
