A TYPE_INDEX operand (as used by call_indirect) used to be represented by the InstPrinter as a symbol (e.g. .Ltype_index0@TYPE_INDEX) which was a bit of a mismatch with the WasmObjectWriter which expects an unnamed symbol, to receive the signature from and then turn into a reloc. There was really no good way to round-trip this information. An earlier version of this patch tried to attach the signature information using a .functype, but that ran into trouble when the symbol was re-emitted without a name. Removing the name was a giant hack also. The current version changes the assembly syntax to have an inline signature spec for TYPEINDEX operands that is always unnamed, which is much more elegant both in syntax and in implementation (as now the assembler is able to follow the same path as the regular backend) Reviewers: sbc100, dschuff, aheejin, jgravelle-google, sunfish, tlively Subscribers: arphaman, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D64758 llvm-svn: 367590 |
