From caae4de6b65ff0b232de942b52ece4cb4e6fbb90 Mon Sep 17 00:00:00 2001 From: mdkinney Date: Thu, 9 Nov 2006 21:26:29 +0000 Subject: Add #define CPU_STACK_ALIGNMENT to the ProcessorBind.h for each of the supported CPU architectures. This value is sizeof(UINTN) for IA-32, X64, and EBC. It is 16 bytes for IPF. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@1920 6f19259b-4bc3-4df7-8a09-765794883524 --- MdePkg/Include/Ipf/ProcessorBind.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'MdePkg/Include/Ipf') diff --git a/MdePkg/Include/Ipf/ProcessorBind.h b/MdePkg/Include/Ipf/ProcessorBind.h index 86374b2249..f3706a782a 100644 --- a/MdePkg/Include/Ipf/ProcessorBind.h +++ b/MdePkg/Include/Ipf/ProcessorBind.h @@ -171,6 +171,12 @@ typedef INT64 INTN; // #define MAX_ADDRESS 0xFFFFFFFFFFFFFFFFULL +// +// Per the Itanium Software Conventions and Runtime Architecture Guide, +// section 3.3.4, IPF stack must always be 16-byte aligned. +// +#define CPU_STACK_ALIGNMENT 16 + // // Modifier to ensure that all protocol member functions and EFI intrinsics // use the correct C calling convention.
