[llvm] [CSKY] Add missing <map> include in CSKYTargetStreamer.h (PR #209384)

[Jim Lin via llvm-commits]

https://github.com/tclin914 created https://github.com/llvm/llvm-project/pull/209384

CSKYTargetStreamer declares a std::map member (CachedEntries) but relied on <map> being pulled in transitively through llvm/MC/ConstantPools.h.

Commit 74cc7fdcc850 ("[MC] Use DenseMap for ConstantPool::CachedEntries. NFC.") switched ConstantPools.h to DenseMap and removed its #include <map>, so the transitive include is gone. Include <map> directly to keep the header self-contained.

Subject: [PATCH] [CSKY] Add missing <map> include in CSKYTargetStreamer.h

CSKYTargetStreamer declares a std::map member (CachedEntries) but relied
on <map> being pulled in transitively through llvm/MC/ConstantPools.h.

Commit 74cc7fdcc850 ("[MC] Use DenseMap for ConstantPool::CachedEntries.
NFC.") switched ConstantPools.h to DenseMap and removed its
#include <map>, so the transitive include is gone. Include <map>
directly to keep the header self-contained.
