This finishes the part 1 of 2 patch submitted by Andrew Burgess on Aug 19. This adds the argument registers but not t0 (aka x5) to SIBCALL_REGS. It also adds the missing riscv_regno_to_class change. Tested with cross riscv32-elf and riscv64-linux toolchain build and check. There were no regressions. I see about a 0.01% code size reduction for the C and libstdc++ libraries. gcc/ * config/riscv/riscv.h (REG_CLASS_CONTENTS): Add argument passing regs to SIBCALL_REGS. * config/riscv/riscv.c (riscv_regno_to_class): Change argument passing regs to SIBCALL_REGS.

The Arm port is failing bootstrap because GCC is now warning about an unitialized array.

In aarch64_classify_symbol symbols are allowed large offsets on relocations. This means the offset can use all of the +/-4GB offset, leaving no offset available for the symbol itself. This results in relocation overflow and link-time errors for simple expressions like &global_array + 0xffffff00. To avoid this, unless the offset_within_block_p is true, limit the offset to +/-1MB so that the symbol needs to be within a 3.9GB offset from its references. For the tiny code model use a 64KB offset, allowing most of the 1MB range for code/data between the symbol and its references. gcc/ * config/aarch64/aarch64.c (aarch64_classify_symbol): Apply reasonable limit to symbol offsets. testsuite/ * gcc.target/aarch64/symbol-range.c: Improve testcase. * gcc.target/aarch64/symbol-range-tiny.c: Likewise.

In PR70010, a function is marked with target(no-vsx) to disable VSX code generation. To avoid VSX code generation, this function should not be inlined into VSX function. To fix the bug, in the current logic when checking whether the caller's ISA flags supports the callee's ISA flags, we just need to add a test that enforces that the caller's ISA flags match exactly the callee's flags, for those flags that were explicitly set in the callee. If caller without target attribute then using options from command line. gcc/ 2019-10-16 Peter Bergner <bergner@linux.ibm.com> Jiufu Guo <guojiufu@linux.ibm.com> PR target/70010 * config/rs6000/rs6000.c (rs6000_can_inline_p): Prohibit inlining if the callee explicitly disables some isa_flags the caller is using. gcc.testsuite/ 2019-10-16 Peter Bergner <bergner@linux.ibm.com> Jiufu Guo <guojiufu@linux.ibm.com> PR target/70010 * gcc.target/powerpc/pr70010.c: New test. * gcc.target/powerpc/pr70010-1.c: New test. * gcc.target/powerpc/pr70010-2.c: New test. * gcc.target/powerpc/pr70010-3.c: New test. * gcc.target/powerpc/pr70010-4.c: New test.

This patch adds extra vector modes that represent a half, quarter or eighth of what an SVE vector can hold. This is useful for describing the memory vector involved in an extending load or truncating store. It might also be useful in future for representing "unpacked" SVE registers, i.e. registers that contain values in the low bits of a wider containing element. The new modes could have the same width as an Advanced SIMD mode for certain -msve-vector-bits=N options, so we need to ensure that they come later in the mode list and that Advanced SIMD modes always "win". 2019-10-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * genmodes.c (mode_data::order): New field. (blank_mode): Update accordingly. (VECTOR_MODES_WITH_PREFIX): Add an order parameter. (make_vector_modes): Likewise. (VECTOR_MODES): Update use accordingly. (cmp_modes): Sort by the new order field ahead of sorting by size. * config/aarch64/aarch64-modes.def (VNx2QI, VN2xHI, VNx2SI) (VNx4QI, VNx4HI, VNx8QI): New partial vector modes. * config/aarch64/aarch64.c (VEC_PARTIAL): New flag value.

I'd used known_lt when converting these conditions to poly_int, but on reflection that was a bad choice. The code isn't just doing a range check; it specifically needs constants that will fit in a certain encoding. 2019-10-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64.c (aarch64_layout_frame): Use is_constant rather than known_lt when choosing frame layouts.

This patch adds an assert that all the individual *_adjust allocations add up to the full frame size. With that safety net, it seemed slightly clearer to use crtl->outgoing_args_size as the final adjustment where appropriate, to match what's used in the comments. This is a bit overkill on its own, but I need to add more cases for SVE. 2019-10-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64.c (aarch64_layout_frame): Assert that all the adjustments add up to the full frame size.

Using the full path "cfun->machine->frame" in aarch64_layout_frame led to awkward formatting in some follow-on patches, so it seemed worth using a local reference instead. 2019-10-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ * config/aarch64/aarch64.c (aarch64_layout_frame): Use a local "frame" reference instead of always referring directly to "cfun->machine->frame".

This patch makes value_range_base::set convert POLY_INT_CST bounds into the worst-case INTEGER_CST bounds. The main case in which this gives useful ranges is a lower bound of A + B * X becoming A when B >= 0. E.g.: [32 + 16X, 100] -> [32, 100] [32 + 16X, 32 + 16X] -> [32, MAX] But the same thing can be useful for the upper bound with negative X coefficients. 2019-10-16 Richard Sandiford <richard.sandiford@arm.com> gcc/ PR middle-end/92033 * poly-int.h (constant_lower_bound_with_limit): New function.
