Reclaim the memory of escape analysis Nodes before kicking off the backend, as they are not needed in get_backend. Reviewed-on: https://go-review.googlesource.com/86243 From-SVN: r256707Ian Lance Taylor committed -
Local variables captured by the deferred closure need to be live until the function finishes, especially when the deferred function runs. In Function::build, for function that has a defer, we wrap the function body in a try block. So the backend sees the local variables only live in the try block, without knowing that they are needed also in the finally block where we invoke the deferred function. Fix this by creating top-level declarations for non-escaping address-taken locals when there is a defer. An example of miscompilation without this CL: func F(fn func()) { didPanic := true defer func() { println(didPanic) }() fn() didPanic = false } With escape analysis turned on, at optimization level -O1 or -O2, the store "didPanic = false" is elided by the backend's optimizer, presumably because it thinks "didPanic" is not live after the store, so the store is useless.

In this wrong-code bug we combine a VSUB.I8 and a VABS.S8 into a VABD.S8 instruction . This combination is not valid for integer operands because in the VABD instruction the semantics are that the difference is computed in notionally infinite precision and the absolute difference is computed on that, whereas for a VSUB.I8 + VABS.S8 sequence the VSUB operation will perform any wrapping that's needed for the 8-bit signed type before the VABS gets its hands on it. This leads to the wrong-code in the PR where the expected sequence from the intrinsics: VSUB + VABS of two vectors {-100, -100, -100...}, {100, 100, 100...} gives a result of {56, 56, 56...} (-100 - 100) but GCC optimises it into a single VABD of {-100, -100, -100...}, {100, 100, 100...} which produces a result of {200, 200, 200...} The transformation is still valid for floating-point operands, which is why it was added in the first place I believe (r178817) but this patch disables it for integer operands. The HFmode variants though only exist for TARGET_NEON_FP16INST, so this patch adds the appropriate guards to the new mode iterator Bootstrapped and tested on arm-none-linux-gnueabihf.

After inlining A into B, inline_small_functions updates the information for (most) callees and callers of the new B: update_callee_keys (&edge_heap, where, updated_nodes); [...] /* Our profitability metric can depend on local properties such as number of inlinable calls and size of the function body. After inlining these properties might change for the function we inlined into (since it's body size changed) and for the functions called by function we inlined (since number of it inlinable callers might change). */ update_caller_keys (&edge_heap, where, updated_nodes, NULL); These functions in turn call can_inline_edge_p for most of the associated edges: if (can_inline_edge_p (edge, false) && want_inline_small_function_p (edge, false)) update_edge_key (heap, edge); can_inline_edge_p indirectly calls estimate_calls_size_and_time on the caller node, which seems to recursively process all callee edges rooted at the node. It looks from this like the algorithm can be at least quadratic in the worst case. Maybe there's something we can do to make can_inline_edge_p cheaper, but since neither of these two calls is responsible for reporting an inline failure reason, it seems cheaper to test want_inline_small_function_p first, so that we don't calculate an estimate for something that we already know isn't a "small function". I think the only change needed to make that work is to check for CIF_FINAL_ERROR in want_inline_small_function_p; at the moment we rely on can_inline_edge_p to make that check. This cuts the time to build optabs.ii by over 4% with an --enable-checking=release compiler on x86_64-linux-gnu. I've seen more dramatic wins on aarch64-linux-gnu due to the NUM_POLY_INT_COEFFS==2 thing.
