<pre>pass the following simple ll file to llc, llc will assert. I have not looked at
in in details.
; ModuleID = '<stdin>'
target datalayout = "e-i64:64-f80:128-n8:16:32:64-S128"
target triple = "x86_64-pc-win64-coff"
@llvm.global_ctors = appending global [1 x { i32, void ()*, i8* }] [{ i32, void
()*, i8* } { i32 0, void ()* @__llvm_profile_init, i8* null }]
; Function Attrs: noinline
define internal void @__llvm_profile_init() unnamed_addr #1 {
ret void
}
attributes #0 = { nounwind }
The assertion failure is:
llc: /usr/local/google/davidxl/dev/llvm/include/llvm/Support/Casting.h:237:
typename cast_retty<X, Y *>::ret_type llvm::cast(Y *) [X = llvm::MCSectionCOFF,
Y = llvm::MCSection]: Assertion `isa<X>(Val) && "cast<Ty>() argument of
incompatible type!"' failed.
