2017-03-06MdeModulePkg: Refine casting expression result to bigger sizeHao Wu1-5/+5
There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

2017-02-28MdeModulePkg/EbcDxe: use EfiBootServicesCode memory for thunksArd Biesheuvel6-4/+41
The EBC driver emits thunks for native to EBC calls, which are short instructions sequences that bridge the gap between the native execution environment and the EBC virtual machine. Since these thunks are allocated using MemoryAllocationLib::AllocatePool(), they are emitted into EfiBootServicesData regions, which does not reflect the nature of these thunks accurately, and interferes with strict memory protection policies that map data regions non-executable. So instead, create a new helper EbcAllocatePoolForThunk() that invokes the AllocatePool() boot service directly to allocate EfiBootServicesCode pool memory explicitly, and wire up this helper for the various architecture specific thunk generation routines.

The prototypes of EbcInterpret() and ExecuteEbcImageEntryPoint() are private to the AARCH64 implementation of EbcDxe, so we can shuffle the arguments around a bit and make the assembler thunking glue a lot simpler. For ExecuteEbcImageEntryPoint(), this involves passing the EntryPoint argument as the third parameter, rather than the first, which allows us to do a tail call. For EbcInterpret(), instead of copying each argument beyond #8 from one native stack frame to the next (before another copy is made into the VM stack), pass a pointer to the argument stack.

The thunk generation is needlessly complex, given that it attempts to deal with variable length instructions, which don't exist on AArch64. So replace it with a simple template coded in assembler, with a matching struct definition in C. That way, we can create and manipulate the thunks easily without looping over the instructions looking for 'magic' numbers. Also, use x16 rather than x9, since it is the architectural register to use for thunks/veneers.
