* Don't use permutes for single-element accesses (PR83753)rsandifo2018-01-104-4/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After cunrolling the inner loop, the remaining loop in the testcase has a single 32-bit access and a group of 64-bit accesses. We first try to vectorise at 128 bits (VF 4), but decide not to for cost reasons. We then try with 64 bits (VF 2) instead. This means that the group of 64-bit accesses uses a single-element vector, which is deliberately supported as of r251538. We then try to create "permutes" for these single-element vectors and fall foul of: for (i = 0; i < 6; i++) sel[i] += exact_div (nelt, 2); in vect_grouped_store_supported, since nelt==1. Maybe we shouldn't even be trying to vectorise statements in the single-element case, and instead just copy the scalar statement for each member of the group. But until then, this patch treats non-strided grouped accesses as VMAT_CONTIGUOUS if no permutation is necessary. 2018-01-10 Richard Sandiford <richard.sandiford@linaro.org> gcc/ PR tree-optimization/83753 * tree-vect-stmts.c (get_group_load_store_type): Use VMAT_CONTIGUOUS for non-strided grouped accesses if the number of elements is 1. gcc/testsuite/ PR tree-optimization/83753 * gcc.dg/torture/pr83753.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@256427 138bc75d-0d04-0410-961f-82ee72b054a4

* runtime: work around escaping closure in export_test.goian2018-01-102-8/+8
| | | | | | | | | | | | | | | | | | | When compiling runtime, it is not allowed for local variables and closures to be heap allocated. In one test, there is a go statement with a closure. In the gc compiler, it distinguishes capturing variable by value vs. by address, and rewrites it to passing the captured values as arguments. Currently we don't have this, and the escape analysis decides to heap allocate the closure and also the captured variables, which is not allowed. Work around it by passing the variables explicitly. This is in preparation of turning on escape analysis for the runtime.

| | | | | | | | | | | | | | | | | | Currently, allocation expression that can be allocated on stack is implemented with __builtin_alloca, which turns into __morestack_allocate_stack_space, which may call C malloc. This may be slow. Also if this happens during certain runtime functions (e.g. write barrier), bad things might happen (when the escape analysis is enabled for the runtime). Make a temporary variable on stack for the allocation instead. Also remove the write barrier in the assignment in building heap expression when it is stack allocated.

| | | | | | | | | | | | | | | The escape analysis models closures by flowing captured variable address to the closure node. However, the escape state for the address expressions remained unset as ESCAPE_UNKNOWN. This caused later passes to conclude that the address escapes. Fix this by setting its escape state to ESCAPE_NONE first. If it escapes (because the closure escapes), the flood phase will set its escape state properly.

| | | | | | | | | | | | | | Move some check of escape state earlier, from get_backend to Mark_address_taken. So we can reclaim escape analysis Nodes before kicking off the backend (not done in this CL). Also it makes it easier to check variables and closures do not escape when the escape analysis is run for the runtime package (also not done in this CL).

* compiler: support go:noescape cross packageian2018-01-094-9/+46
| | | | | | | | | | | | | | | CL 83876 added support of go:noescape pragma, but it only works for functions called from the same package. The pragma did not take effect for exported functions that are not called from the same package. The reason is that top level function declarations are not traversed, and only reached from calls from other functions. This CL adds this support. The Traverse class is extended with a mode to traverse function declarations.

| | | | | | | | | | | | | If we're making a slice of constant size that does not need to escape, allocate it on stack. In lower, do not create temporaries for constant size makeslice, so that it is easier to detect the slice is constant size later.

| | | | | | | | | | | | Arrays that are sliced are set to escape in type checking, very early in compilation. The escape analysis runs later but cannot undo it. This CL changes it to not escape in the early stage. Later the escape analysis will make it escape when needed.

| | | | | | | | | | | | | | | | | | If a local variable's address is taken and passed out of its lexical scope, GCC backend may reuse the stack slot for the variable, not knowing it is still live through a pointer. In this case, we create a top-level temporary variable and let the user-defined variable refer to the temporary variable as its storage location. As the temporary variable is declared at the top level, its stack slot will remain live throughout the function.
