LGTM. After some further consideration, implementing this properly in LLVM
would probably take more effort than is worthwhile (especially as this is
target-specific functionality, so we'd actually have to expose TTI queries for
this, etc.)
================
Comment at: clang/lib/CodeGen/CGStmt.cpp:2734
+ llvm::Value *IsBooleanValue =
+ Builder.CreateCmp(llvm::CmpInst::ICMP_ULE, Tmp, OneVal);
+ llvm::Function *FnAssume = CGM.getIntrinsic(llvm::Intrinsic::assume);
----------------
The canonical form of this is `< 2` rather than `<= 1`.
================
Comment at: clang/test/CodeGen/inline-asm-x86-flag-output.c:378
+
+int test_assume_boolean_flag(long nr, volatile long *addr) {
+ //CHECK-LABEL: @test_assume_boolean_flag
----------------
You might want to check that we're doing the right thing if there are multiple
output constraints (via extractvalue).
