2021-12-28Libbacktrace: Fix the use of newline in sed replacementFrancois-Xavier Coudert2-8/+8
On non-ELF targets, the Makefile needs a newline inside the sed REPLACE string. The way it is currently done fails with GNU Make < 4, but GCC only requires "GNU make version 3.80 (or later)".

Some time ago I've changed const_binop -> wide_int_binop, so that it punts on shifts by negative count. fold_truth_andor_1 doesn't check the results of const_binop (?SHIFT_EXPR, ) though and assumes they will be always non-NULL, which is no longer the case. 2021-12-28 Jakub Jelinek <jakub@redhat.com> PR middle-end/103813 * fold-const.c (fold_truth_andor_1): Punt of const_binop LSHIFT_EXPR or RSHIFT_EXPR returns NULL.

2021-12-28loop-invariant: Fix -fcompare-debug failure [PR103837]Jakub Jelinek2-4/+34
In the following testcase we have a -fcompare-debug failure, because can_move_invariant_reg doesn't ignore DEBUG_INSNs in its decisions. In the testcase we have due to uninitialized variable: loop_header debug_insn using pseudo84 pseudo84 = invariant insn using pseudo84 end loop and with -g decide not to move the pseudo84 = invariant before the loop header; in this case not resetting the debug insns might be fine. But, we could have also: pseudo84 = whatever loop_header debug_insn using pseudo84 pseudo84 = invariant insn using pseudo84 end loop and in that case not resetting the debug insns would result in wrong-debug. And, we don't really have generally a good substitution on what pseudo84 contains, it could inherit various values from different paths. So, the following patch ignores DEBUG_INSNs in the decisions, and if there are any that previously prevented the optimization, resets them before return true. 2021-12-28 Jakub Jelinek <jakub@redhat.com> PR rtl-optimization/103837 * loop-invariant.c (can_move_invariant_reg): Ignore DEBUG_INSNs in the decisions whether to return false or continue and right before returning true reset those debug insns that previously caused returning false. * gcc.dg/pr103837.c: New test.
2021-12-28optabs: Fix up checking for CALLs in newly added code by double-word divmod ↵Jakub Jelinek2-0/+36
[PR103838] These two spots are meant to punt if the newly added code contains any CALL_INSNs, because in that case having a large sequence of insns that also calls something is undesirable, better have one call that is optimized in itself well. The functions do last = get_last_insn (); before emitting any insns (and expand_binop as the ultimate caller uses delete_insns_since if the expansion fails), but the checks were incorrect for 2 reasons: 1) it checked not just what follows after that last insn, but also the last insn itself; so, if the division or modulo is immediately preceded by a CALL_INSN, then we punt; this also causes -fcompare-debug failures if the CALL_INSN is with -g followed by one or more DEBUG_INSNs 2) if get_last_insn () is NULL (i.e. emitting into a new sequence), then we didn't check anything 2021-12-28 Jakub Jelinek <jakub@redhat.com> PR debug/103838 * optabs.c (expand_doubleword_mod, expand_doubleword_divmod): Only check newly added insns for CALL_P, not the last insn of previous code. * gcc.dg/pr103838.c: New test.

2021-12-28driver: Improve option diagnostics [PR103465]Martin Liska3-57/+72
It happens that options are parsed and various diagnostics happen in finish_options. That's a proper place as the function is also called for optimize/target attributes (pragmas). However, it is possible that target overwrites an option from command line and so the diagnostics does not happen.

2021-12-27ix86: Don't use the 'm' constraint for x86_64_general_operandH.J. Lu5-32/+706
The 'm' constraint is defined with define_memory_constraint which allows LRA to convert the operand to the form '(mem (reg X))', where X is a base register. To prevent LRA from generating '(mem (reg X))' from a register: 1. Add a 'BM' constraint which is similar to the 'm' constraint, but is defined with define_constraint. 2. Add a 'm' mode attribute which is mapped to the 'm' constraint for general_operand and the 'BM' constraint for x86_64_general_operand. 3.

The current rule was too strict and has not been required since Darwin11. This relaxes the constraint to allow up to 2^28 alignment for non-common entities. Common is still restricted to a maximum aligment of 2^15. When the host is an older version of Darwin ( earlier that 11 ) then the existing constraint is still applied. Note that this is a host constraint not a target one (so that a compilation on 10.7 targeting 10.6 is allowed to use a greater alignment than the tools on 10.6 support).

Move the implementation of MVE ACLE types from arm_mve_types.h to inside GCC via a new pragma, which replaces the prior type definitions. This allows for the types to be used internally for intrinsic function definitions. gcc/ChangeLog: * config.gcc (arm*-*-*): Add arm-mve-builtins.o to extra_objs. * config/arm/arm-c.c (arm_pragma_arm): Handle "#pragma GCC arm". (arm_register_target_pragmas): Register it. * config/arm/arm-protos.h: (arm_mve::arm_handle_mve_types_h): New prototype. * config/arm/arm_mve_types.h: Replace MVE type definitions with new pragma. * config/arm/t-arm: (arm-mve-builtins.o): New target rule. * config/arm/arm-mve-builtins.cc: New file. * config/arm/arm-mve-builtins.def: New file. * config/arm/arm-mve-builtins.h: New file. gcc/testsuite/ChangeLog: * gcc.target/arm/mve/mve.exp: Add new subdirectories. * gcc.target/arm/mve/general-c/type_redef_1.c: New test. * gcc.target/arm/mve/general/double_pragmas_1.c: New test. * gcc.target/arm/mve/general/nomve_1.c: New test.
2021-12-22arm: Move arm_simd_info array declaration into headerMurray Steele2-86/+88
Move the arm_simd_type and arm_type_qualifiers enums, and arm_simd_info struct from arm-builtins.c into arm-builtins.h header. This is a first step towards internalising the type definitions for MVE predicate, vector, and tuple types. By moving arm_simd_types into a header, we allow future patches to use these type trees externally to arm-builtins.c, which is a crucial step towards developing an MVE intrinsics framework similar to the current SVE implementation. gcc/ChangeLog: * config/arm/arm-builtins.c (enum arm_type_qualifiers): Move to arm_builtins.h. (enum arm_simd_type): Move to arm-builtins.h. (struct arm_simd_type_info): Move to arm-builtins.h. * config/arm/arm-builtins.h (enum arm_simd_type): Move from arm-builtins.c. (enum arm_type_qualifiers): Move from arm-builtins.c. (struct arm_simd_type_info): Move from arm-builtins.c.
2021-12-22Fortran: allow __float128 on targets where long double is not REAL(KIND=10)Francois-Xavier Coudert2-20/+9
The logic for detection of REAL(KIND=16) in kinds-override.h made assumptions: -- if real(kind=10) exists, i.e. if HAVE_GFC_REAL_10 is defined, then it is necessarily the "long double" type -- if real(kind=16) exists, then: * if HAVE_GFC_REAL_10, real(kind=16) is "__float128" * otherwise, real(kind=16) is "long double" This may not always be true. Take the aarch64-apple-darwin port, it has double == long double == binary64, and __float128 == binary128. We already have more fine-grained logic in the mk-kinds-h.sh script, where we actually check the Fortran kind corresponding to C’s long double. So let's use it, and emit the GFC_REAL_16_IS_FLOAT128 / GFC_REAL_16_IS_LONG_DOUBLE macros there. libgfortran/ChangeLog: * kinds-override.h: Move GFC_REAL_16_IS_* macros... * mk-kinds-h.sh: ... here.

As well as checking for the existence of a GDC compiler, also validate that it has also been built with libphobos, otherwise warn or fail with the message that GDC is required to build d. config/ChangeLog: PR d/103528 * acx.m4 (ACX_PROG_GDC): Add check whether D compiler works. ChangeLog: * configure: Regenerate.
2021-12-21libphobos: Add power*-*-freebsd* as supported targetIain Buclaw1-0/+3
This has been tested on powerpc64-freebsd13 and powerpc64le-freebsd13, and used to build dub, along with some D tools from ports. libphobos/ChangeLog: * configure.tgt: Add power*-*-freebsd* as a supported target.
