2022-06-19expand: Fix up IFN_ATOMIC_{BIT*,*CMP_0} expansion [PR105951]Jakub Jelinek4-16/+64
Both IFN_ATOMIC_BIT_TEST_AND_* and IFN_ATOMIC_*_FETCH_CMP_0 ifns are matched if their corresponding optab is implemented for the particular mode. The fact that those optabs are implemented doesn't guarantee they will succeed though, they can just FAIL in their expansion. The expansion in that case uses expand_atomic_fetch_op as fallback, but as has been reported and and can be reproduced on the testcases, even those can fail and we didn't have any fallback after that. For IFN_ATOMIC_BIT_TEST_AND_* we actually have such calls. One is done whenever we lost lhs of the ifn at some point in between matching it in tree-ssa-ccp.cc and expansion. The following patch for that case just falls through and expands as if there was a lhs, creates a temporary for it. For the other expand_atomic_fetch_op call in the same expander and for the only expand_atomic_fetch_op call in the other, this falls back the hard way, by constructing a CALL_EXPR to the call from which the ifn has been matched and expanding that. Either it is lucky and manages to expand inline, or it emits a libatomic API call. So that we don't have to rediscover which builtin function to call in the fallback, we record at tree-ssa-ccp.cc time gimple_call_fn (call) in an extra argument to the ifn. 2022-06-16 Jakub Jelinek <jakub@redhat.com> PR middle-end/105951 * tree-ssa-ccp.cc (optimize_atomic_bit_test_and, optimize_atomic_op_fetch_cmp_0): Remember gimple_call_fn (call) as last argument to the internal functions. * builtins.cc (expand_ifn_atomic_bit_test_and): Adjust for the extra call argument to ifns.

2022-06-19c++: Fix up ICE on __builtin_shufflevector constexpr evaluation [PR105871]Jakub Jelinek2-3/+22
As the following testcase shows, BIT_FIELD_REF result doesn't have to have just integral type, it can also have vector type. And in that case cxx_eval_bit_field_ref just ICEs on it because it is unprepared for that case, creates the initial value with build_int_cst (sure, that one could be easily replaced with build_zero_cst) and then expects it can through shifts, ands and ors come up with the final value, but that doesn't work for vectors. We already call fold_ternary if whole is a VECTOR_CST, this patch does the same if the result doesn't have integral type. And, there is no guarantee fold_ternary will succeed and the callers certainly don't expect NULL being returned, so it also diagnoses those as non-constant and returns original t in that case. 2022-06-09 Jakub Jelinek <jakub@redhat.com> PR c++/105871 * constexpr.cc (cxx_eval_bit_field_ref): For BIT_FIELD_REF with non-integral result type use fold_ternary too like for BIT_FIELD_REFs from VECTOR_CST.

2022-06-16arm: big-endian issue in gen_cpymem_ldrd_strd [PR105981]Richard Earnshaw1-8/+16
The code in gen_cpymem_ldrd_strd has been incorrect for big-endian since r230663. The problem is that we use gen_lowpart, etc. to split the 64-bit quantity, but fail to account for the fact that these routines are really dealing with 64-bit /values/ and in big-endian the ordering of the sub-registers changes. To fix this, I've renamed the conceptually misnamed low_reg and hi_reg as first_reg and second_reg, and then used different logic for big-endian targets to initialize these values. This makes the logic clearer than trying to think about high bits and low bits. gcc/ChangeLog: PR target/105981 * config/arm/arm.cc (gen_cpymem_ldrd_strd): Rename low_reg and hi_reg to first_reg and second_reg respectively.

2022-06-15Darwin: Truncate kernel-provided version to OS major for Darwin >= 20.Simon Wright1-11/+5
In common with system tools, GCC uses a version obtained from the kernel as the prevailing macOS target, when that is not overridden by command line or environment versions (i.e. mmacosx-version-min=, MACOSX_DEPLOYMENT_TARGET). Presently, GCC assumes that if the OS version is >= 20, the value used should include both major and minium version identifiers. However the system tools (for those versions) truncate the value to the major version - this leads to link errors when combining objects built with clang and GCC for example: ld: warning: object file (null.o) was built for newer macOS version (12.2) than being linked (12.0) The change here truncates the values GCC uses to the major version. gcc/ChangeLog: PR target/104871 * config/darwin-driver.cc (darwin_find_version_from_kernel): If the OS version is darwin20 (macOS 11) or greater, truncate the version to the major number.

2022-06-15Darwin: Future-proof -mmacosx-version-minMark Mentovai1-1/+2
f18cbc1ee1f4 (2021-12-18) updated various parts of gcc to not impose a Darwin or macOS version maximum of the current known release. Different parts of gcc accept, variously, Darwin version numbers matching darwin2*, and macOS major version numbers up to 99. The current released version is Darwin 21 and macOS 12, with Darwin 22 and macOS 13 expected for public release later this year. With one major OS release per year, this strategy is expected to provide another 8 years of headroom. However, f18cbc1ee1f4 missed config/darwin-c.c (now .cc), which continued to impose a maximum of macOS 12 on the -mmacosx-version-min compiler driver argument. This was last updated from 11 to 12 in 11b967577483 (2021-10-27), but kicking the can down the road one year at a time is not a viable strategy, and is not in line with the more recent technique from f18cbc1ee1f4. Prior to 556ab5125912 (2020-11-06), config/darwin-c.c did not impose a maximum that needed annual maintenance, as at that point, all macOS releases had used a major version of 10. The stricter approach imposed since then was valuable for a time until the particulars of the new versioning scheme were established and understood, but now that they are, it's prudent to restore a more permissive approach. gcc/ChangeLog: * config/darwin-c.cc: Make -mmacosx-version-min more future-proof.

2022-06-15Darwin: Fix empty g++ command lines [PR105599].Iain Sandoe1-11/+6
An empty g++ command line should produce a diagnostic that there are no inputs. The PR is that currently Darwin produces a dignostic about missing link items instead - this is because (errnoeously), for this driver, we are creating a link job for empty command lines. The problem occurs in four stages: The g++ driver appends -shared-libgcc to the command line. The Darwin driver_init code in the backend does not see this (it sees an empty command line). When the back end driver code driver sees an empty command line, it does not add any supplementary flags (e.g. asm-macosx-version-min) - precisely to avoid anything being claimed as an input_file and therefore triggering a link line. Since we do not have a value for asm-macosx-version-min when processing the driver specs, we unconditionally inject 'multiply_defined suppress' which is used with shared libgcc (but only intended on very old Darwin). This then causes the generation of a link job. The solution, for the present, is to move version-specific link params to the LINK_SPEC so that they are only processed when a link job has already been decided.

The existing TypeInfo errors can be cryptic. This alters the diagnostic to include which expression is requiring `object.TypeInfo'. gcc/d/ChangeLog: * d-tree.h (check_typeinfo_type): Add Expression* parameter. (build_typeinfo): Likewise. Declare new override. * expr.cc (ExprVisitor): Call build_typeinfo with Expression*. * typeinfo.cc (check_typeinfo_type): Include expression in the diagnostic message. (build_typeinfo): New override. gcc/testsuite/ChangeLog: * gdc.dg/rtti1.d: New test. (cherry picked from commit e55eda238545e93708c020fd21249459be64c463)
