2015-03-27MdePkg: fix ARM version of InternalMathSwapBytes64 ()Ard Biesheuvel
The ARM asm implementation of InternalMathSwapBytes64 () does interesting things if bit 7 of operand r1 (upper 32 bits of the input value) is set. After the recursive swap, bit 7 ends up in the sign bit position, after which it is right shifted with sign extension, and or'ed with the upper half of the output value. This means SwapBytes64 (0x00000080_00000000) returns an incorrect value of 0xFFFFFFFF_80000000.

2011-11-08MdePkg/BaseLib: Replaced inline assembly for ARMGCC by GCC assembly source fileoliviermartin
The registers used to passed arguments to the DxeCore entrypoint in the inline assembly function InternalSwitchStackAsm() where switched at compilation time. This change replaces the inline assembly by a pure assembly source file to avoid this kind of optimization. Note: Inline assembly is generally not recommanded in system programming.

2011-02-01Replace INTERWORK_FUNC, with GCC_ASM_EXPORT() and GCC_ASM_IMPORT() and ↵andrewfish
update the rest of the MdePkg ARM assembler to use the macro. Leave the old INTERWORK_FUNC macro in place until we can make sure all the other packages have been updated and then it can be removed. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11289 6f19259b-4bc3-4df7-8a09-765794883524
2010-12-15Fix issue with CodeSourcery gcc requiring assembly functions to have a .type ↵andrewfish
