This patch fixes an issue in aarch64_classify_address. TImode and TFmode can either use a 64-bit LDP/STP or 128-bit LDR/STR. The addressing mode must be carefully modelled as the intersection of both. This is done for the immediate offsets, however load_store_pair_p must be set as well to avoid LDP with a PC-relative address if aarch64_pcrelative_literal_loads is true. gcc/ PR target/78733 * config/aarch64/aarch64.c (aarch64_classify_address): Set load_store_pair_p for TImode and TFmode. testsuite/ * gcc.target/aarch64/pr78733.c: New test.

Rewrite the AES hashing code from gc assembler to C code using intrinsics. The resulting code generates the same hash code for the same input as the gc code--that doesn't matter as such, but testing it ensures that the C code does something useful. Also change mips64pe32le to mips64p32le in configure script--noticed during CL review. Reviewed-on: https://go-review.googlesource.com/34022 From-SVN: r243445Ian Lance Taylor committed -
The gc library allocates a _panic struct on the stack. This does not work for gccgo, because when a deferred function recovers the panic we unwind the stack up to that point so that returning from the function will work correctly. Allocating on the stack fine if the panic is not recovered, and it works fine if the panic is recovered by a function that returns. However, it fails if the panic is recovered by a function that itself panics, and if that second panic is then recovered by a function higher up on the stack. When we unwind the stack to that second panic, the g will wind up pointing at a panic farther down on the stack. Even then everything will often work fine, except when the deferred function catching the second panic makes a bunch of calls that use stack space before returning. In that case the code can overwrite the panic struct, which will then cause disaster when we remove the struct from the linked list, as the link field will be garbage. This case is rare enough that all the x86 tests were passing, but there was a failure on ppc64le. Before https://golang.org/cl/33414 we allocated the panic struct on the heap, so go back to doing that again. Fixes golang/go#18228.

Because of the way we handle call expressions with multiple results, it's possible for expressions to be flattened more than once. In the case of Slice_construction_expression, allocating the slice storage multiple times caused a compiler crash as one of the Temporary_statement's wound up not getting a backend expression.

This moves read_rtx and friends into rtx_reader, and splits rtx_reader into two classes: class md_reader: has responsibility for reading chars, managing include files, top-level directives etc. It is the read-md.o part. class rtx_reader, a subclass, has the code for reading hierarchical rtx expressions using the format codes. It is the read-rtl.o part. This split is needed by a followup patch, which converts read_rtx_operand to a virtual function of rtx_reader. To do this, instances of rtx_reader (or its subclasses) need a vtable, which needs to include a ptr to the code in read-rtl.o.
