From f24ff6e9b5adc7983c3ad7cf28375eb49921b3ed Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Fri, 21 Sep 2018 10:27:48 -0400 Subject: [PATCH] csky-opc.h: Initialize fields of last array elements clang gives these errors: In file included from /Users/simark/src/binutils-gdb/opcodes/csky-dis.c:30: /Users/simark/src/binutils-gdb/opcodes/csky-opc.h:2330:8: error: missing field 'transfer' initializer [-Werror,-Wmissing-field-initializers] {NULL} ^ /Users/simark/src/binutils-gdb/opcodes/csky-opc.h:8126:10: error: missing field 'transfer' initializer [-Werror,-Wmissing-field-initializers] {NULL} ^ They go away when we Initialize all fields. I noticed there used to be some files built with -Wno-missing-field-initializers, but it's not the case anymore, since commit e7ae278d0474ab84ba3b1ee932a19e83616ddacc. There is still a NO_WMISSING_FIELD_INITIALIZERS variable defined in the Makefile, but it's unused, so I removed it to avoid further confusion. opcodes/ChangeLog: * Makefile.am: Remove NO_WMISSING_FIELD_INITIALIZERS. * Makefile.in: Re-generate. * aclocal.m4: Re-generate. * configure: Re-generate. * configure.ac: Remove check for -Wno-missing-field-initializers. * csky-opc.h (csky_v1_opcodes): Initialize all fields of last element.
