-Subject: [PATCH] crypto: lib/curve25519 - work around Clang stack spilling
- issue
-
-commit 660bb8e1f833ea63185fe80fde847e3e42f18e3b upstream.
-
-Arnd reports that the 32-bit generic library code for Curve25119 ends
-up using an excessive amount of stack space when built with Clang:
-
-  lib/crypto/curve25519-fiat32.c:756:6: error: stack frame size
-      of 1384 bytes in function 'curve25519_generic'
-      [-Werror,-Wframe-larger-than=]
-
-Let's give some hints to the compiler regarding which routines should
-not be inlined, to prevent it from running out of registers and spilling
-to the stack. The resulting code performs identically under both GCC
-and Clang, and makes the warning go away.
