+Subject: mark internal codegen helpers to be hidden
+Date: Sat, 04 Jan 2025 13:53:36 +0300
+Forwarded: not-needed
+
+QEMU TCG uses arrays of pointers to functions for its
+code generator.  In 7.2, these functions are declared as
+static inline.  However, at least on some platforms, GCC
+tries to make these functions visible to be used in a DSO.
+And this makes the linker to fail at least on some platforms,
+https://gitlab.com/qemu-project/qemu/-/issues/1129.
+
+Mark the internal generated helper functions to have hidden
+visibility, so gcc does not generate code for sharing them,
+which makes GOT significantly smaller (and the actual code
+to access these functions a bit more efficient too).
+
+In later versions, qemu changed this place to use different
+way, so this problem does not exist in more recent qemu.
