Author: Pierre-Emmanuel Patry <pierre-emmanuel.pa...@embecosm.com>
Date: Thu Apr 10 13:05:15 2025 +0200
Add llvmInlineAsm node
InlineAsm node does not support memory clobbers.
gcc/rust/ChangeLog:
* ast/rust-ast-collector.cc (TokenCollector::visit): Make visitor
unreachable.
* ast/rust-ast-collector.h: Add visit for LlvmInlineAsmNode.
* ast/rust-ast-visitor.cc (DefaultASTVisitor::visit): Add visit
function for the default ast visitor.
* ast/rust-ast-visitor.h: Add function prototype.
* ast/rust-ast.cc (LlvmInlineAsm::accept_vis): Add accept_vis to
LlvmInlineAsm node.
* ast/rust-ast.h: Add LlvmInlineAsm node kind.
* ast/rust-expr.h (class LlvmInlineAsm): Add LlvmInlineAsm node.
* expand/rust-derive.h: Add visit function for LlvmInlineAsm node.
* expand/rust-macro-builtins-asm.cc
(MacroBuiltin::llvm_asm_handler):
Add handler for llvm inline assembly nodes.
(parse_llvm_asm): Add function to parse llvm assembly nodes.
* expand/rust-macro-builtins-asm.h (parse_llvm_asm): Add function
prototypes.
* expand/rust-macro-builtins.cc (inline_llvm_asm_maker): Add macro
transcriber.
* expand/rust-macro-builtins.h: Add transcriber function prototype.
* hir/rust-ast-lower-base.cc (ASTLoweringBase::visit): Add visit
function for LlvmInlineAsm node.
* hir/rust-ast-lower-base.h: Add visit function prototype.
* resolve/rust-ast-resolve-base.cc (ResolverBase::visit): Add visit
function for LlvmInlineAsm node.
* resolve/rust-ast-resolve-base.h: Add visit function prototype.
