2020-10-27Refactor array descriptor field accessRichard Biener1-128/+56
This refactors the array descriptor component access tree building to commonize code into new helpers to provide a single place to fix correctness issues with respect to TBAA. The only interesting part is the gfc_conv_descriptor_data_get change to drop broken special-casing of REFERENCE_TYPE desc which, when hit, would build invalid GENERIC trees, missing an INDIRECT_REF before subsetting the descriptor with a COMPONENT_REF. 2020-10-16 Richard Biener <rguenther@suse.de> gcc/fortran/ChangeLog: * trans-array.c (gfc_get_descriptor_field): New helper.

2020-10-27SLP vectorize across PHI nodesRichard Biener24-235/+1031
This makes SLP discovery detect backedges by seeding the bst_map with the node to be analyzed so it can be picked up from recursive calls. This removes the need to discover backedges in a separate walk. This enables SLP build to handle PHI nodes in full, continuing the SLP build to non-backedges. For loop vectorization this enables outer loop vectorization of nested SLP cycles and for BB vectorization this enables vectorization of PHIs at CFG merges. It also turns code generation into a SCC discovery walk to handle irreducible regions and nodes only reachable via backedges where we now also fill in vectorized backedge defs. This requires sanitizing the SLP tree for SLP reduction chains even more, manually filling the backedge SLP def. This also exposes the fact that CFG copying (and edge splitting until I fixed that) ends up with different edge order in the copy which doesn't play well with the desired 1:1 mapping of SLP PHI node children and edges for epilogue vectorization. I've tried to fixup CFG copying here but this really looks like a dead (or expensive) end there so I've done fixup in slpeel_tree_duplicate_loop_to_edge_cfg instead for the cases we can run into. There's still NULLs in the SLP_TREE_CHILDREN vectors and I'm not sure it's possible to eliminate them all this stage1 so the patch has quite some checks for this case all over the place. Bootstrapped and tested on x86_64-unknown-linux-gnu.

2020-10-27d: Merge upstream dmd 0fcdaab32Iain Buclaw9-4/+216
Fixes a bug where there was undefined template references when compiling upstream dmd mainline. In `TemplateInstance::semantic`, there exists special handling of matching template instances for the same template declaration to ensure that only at most one instance gets codegen'd. If the primary instance `inst` originated from a non-root module, the `minst` field will be updated so it is now coming from a root module, however all Dsymbol `inst->members` of the instance still have their `_scope->minst` pointing at the original non-root module. We must now propagate `minst` to all members so that forward referenced dependencies that get instantiated will also be appended to the root module, otherwise there will be undefined references at link-time. This doesn't affect compilations where all modules are compiled together, as every module is a root module in that situation. What this primarily affects are cases where there is a mix of root and non-root modules, and a template was first instantiated in a non-root context, then later instantiated again in a root context.

2020-10-26Handle signed 1-bit ranges in irange::invert.Aldy Hernandez3-8/+54
The problem here is we are trying to add 1 to a -1 in a signed 1-bit field and coming up with UNDEFINED because of the overflow. Signed 1-bits are annoying because you can't really add or subtract one, because the one is unrepresentable. For invert() we have a special subtract_one() function that handles 1-bit signed fields. This patch implements the analogous add_one() function so that invert works. gcc/ChangeLog: PR tree-optimization/97555 * range-op.cc (range_tests): Test 1-bit signed invert. * value-range.cc (subtract_one): Adjust comment.

2020-10-26Implement three-level optimize_for_size predicatesJan Hubicka4-25/+76
this patch implements thre two-state optimize_for_size predicates, so with -Os and with profile feedback for never executed code it returns OPTIMIZE_SIZE_MAX while in cases we decide to optimize for size based on branch prediction logic it return OPTIMIZE_SIZE_BALLANCED. The idea is that for places where we guess that code is unlikely we do not want to do extreme optimizations for size that leads to many fold slowdowns (using idiv rather than few shigts or using rep based inlined stringops). I will update RTL handling code to also support this with BB granuality (which we don't currently). LLVM has -Os and -Oz levels where -Oz is our -Os and LLVM's -Os would ocrrespond to OPTIMIZE_SIZE_BALLANCED. I wonder if we want to export this to command line somehow? For me it would be definitly useful to test things, I am not sure how "weaker" -Os is desired in practice. gcc/ChangeLog: * cgraph.h (cgraph_node::optimize_for_size_p): Return optimize_size_level.
