Dan Gohman	8f5a7d69cc	[WebAssembly] Add support for using a wasm global for the stack pointer. This replaces the __stack_pointer variable which was allocated in linear memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@296201 91177308-0d34-0410-b5e6-96231b3b80d8	2017-02-24 23:46:05 +00:00
Derek Schuff	9ebd8435df	[WebAssembly] Emit a BasePointer when we have overly-aligned stack objects Because we shift the stack pointer by an unknown amount, we need an additional pointer. In the case where we have variable-size objects as well, we can't reuse the frame pointer, thus three pointers.

[WebAssembly] Add support for using a wasm global for the stack pointer.

This replaces the __stack_pointer variable which was allocated in linear
memory.

[WebAssembly] Emit a BasePointer when we have overly-aligned stack objects

Because we shift the stack pointer by an unknown amount, we need an
additional pointer. In the case where we have variable-size objects
as well, we can't reuse the frame pointer, thus three pointers.
