IMO using `-` for stdout is a common practive in UNIX?
e.g.
- `ls -la | vim -`
- `wget -O - https://example.com`
in LLVM ecosystem, Clang already supports this:
```
zeyi2@PhantomParty:tmp% clang -S -emit-llvm a.c -o -
; ModuleID = 'a.c'
source_filename = "a.c"
target datalayout =
"e-m:o-p270:32:32-p271:32:32-p272:64:64-i64:64-i128:128-n32:64-S128-Fn32"
target triple = "arm64-apple-macosx26.0.0"
; Function Attrs: noinline nounwind optnone ssp uwtable(sync)
define i32 @main() #0 {
%1 = alloca i32, align 4
store i32 0, ptr %1, align 4
ret i32 0
}
attributes #0 = { noinline nounwind optnone ssp uwtable(sync)
"frame-pointer"="non-leaf" "no-trapping-math"="true"
"probe-stack"="__chkstk_darwin" "stack-protector-buffer-size"="8"

}
!llvm.module.flags = !{!0, !1, !2, !3, !4}
!llvm.ident = !{!5}
!0 = !{i32 2, !"SDK Version", [2 x i32] [i32 27, i32 0]}
!1 = !{i32 1, !"wchar_size", i32 4}
!2 = !{i32 8, !"PIC Level", i32 2}
!3 = !{i32 7, !"uwtable", i32 1}
!4 = !{i32 7, !"frame-pointer", i32 1}
!5 = !{!"Apple clang version 21.0.0 (clang-2100.3.34.2)"}
```
So personally I think this is fine?
