At the moment we rely on SYMBOL_REF_DECL to get the ABI of the callee of a call insn, falling back to the default ABI if the decl isn't available. I think it'd be cleaner to attach the ABI directly to the call instruction instead, which would also have the very minor benefit of handling indirect calls more efficiently. 2019-10-01 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64-protos.h (aarch64_expand_call): Take an extra callee_abi argument. * config/aarch64/aarch64.c (aarch64_expand_call): Likewise. Insert a CALLEE_ABI unspec into the call pattern as the second element in the PARALLEL. (aarch64_simd_call_p): Delete. (aarch64_insn_callee_abi): Get the arm_pcs of the callee from the new CALLEE_ABI element of the PARALLEL. (aarch64_init_cumulative_args): Get the arm_pcs of the callee from the function type, if given. (aarch64_function_arg_advance): Handle ARM_PCS_SIMD. (aarch64_function_arg): Likewise. Return the arm_pcs of the callee when passed the function_arg_info end marker. (aarch64_output_mi_thunk): Pass the arm_pcs of the callee as the final argument of gen_sibcall. * config/aarch64/aarch64.md (UNSPEC_CALLEE_ABI): New unspec. (call): Make operand 2 a const_int_operand and pass it to expand_call. Wrap it in an UNSPEC_CALLEE_ABI unspec for the dummy define_expand pattern. (call_value): Likewise operand 3. (sibcall): Likewise operand 2. Place the unspec before rather than after the return. (sibcall_value): Likewise operand 3. (*call_insn, *call_value_insn): Include an UNSPEC_CALLEE_ABI. (tlsgd_small_<mode>, *tlsgd_small_<mode>): Likewise. (*sibcall_insn, *sibcall_value_insn): Likewise. Remove empty constraint strings. (untyped_call): Pass const0_rtx as the callee ABI to gen_call. gcc/testsuite/ * gcc.target/aarch64/torture/simd-abi-10.c: New test. * gcc.target/aarch64/torture/simd-abi-11.c: Likewise.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
