Liming, Platform maintainers can decide whether or not they want to combat *binary corruption*? Excuse me, but what the bloody hell? This needs a root cause analysis for which part of the stack silent

Currently, we use the non-Xcode5 version of ExceptionHandlerAsm.nasm only for the SEC and PEI phases, and this version was not compatible with the XCODE or LLD linkers, which do not permit absolute re

Modify CreateIdentityMappingPageTables() to create page table based on CpuPageTableLib in DxeIpl module. This function can be used to create both IA32 PAE paging and long mode 4-level, 5-level paging

The CPU exception handler library code was rewritten at some point to populate the vector code templates with absolute references at runtime, given that the XCODE linker does not permit absolute refer

Adding code to support Cache Management Operations (CMO) defined by RV spec https://github.com/riscv/riscv-CMOs Notes: 1. CMO only supports block based Operations. Meaning complete cache flush/invd/cl

Current implementation for cache management (instruction/data flush/invd) depends on fence.i instruction. All RV platforms may not use the same method for cache management. Instead RV defines CMO Cach

In IA32 code, remove the duplicated code to enable NX. In the previous patch, IA32 code also uses the new CreateIdentityMappingPageTables() to create PAE page table. This function calls EnableExecuteD

We rely on PIE executables to get the codegen that is suitable for PE/COFF conversion where the resulting executables can be loaded anywhere in the address space. However, ELF linkers may default to d

Recent versions of the XCODE linker can be instructed to permit text relocations, so we no longer have to work around this, which is especially nice as our workaround assumes that the .text section is
