Instead of relying on the builtin linker script of GNU ld, which may vary based on binutils version (which is not tightly coupled to the GCC version) and linker command line options, introduce a linker script for AArch64 to be used by all GCC/binutils versions. The script is laid out such that two ELF sections .text and .data are created that map onto the PE/COFF with the same names. By aligning .data to the minimum alignment of .text, and by not adding any additional padding -which is what LD's builtin linker script does- the relative offset between .text and .data is retained after the PE/COFF conversion. This should prevent problems with debuggers and other tooling that are ELF based. Also provided is an overlay linker script that increases the alignment of .text and .data to 64 KB. This is intended for DXE_RUNTIME_DRIVER modules, to make them compatible with the newly introduced Properties Table feature.

This directory contains the next generation of EDK II build tools and template files. Templates are located in the Conf directory, while the tools executables for Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory, other directory contatins tools source. 1. Build step to generate the binary tools. === Windows/Visual Studio Notes === To build the BaseTools, you should run the standard vsvars32.bat script. In addition to this, you should set the following environment variables: * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree * BASE_TOOLS_PATH - The directory where the BaseTools source is located. (It is the same directory where this README.txt is located.) * PYTHON_FREEZER_PATH - Path to where the python freezer tool is installed After this, you can run the toolsetup.bat file, which is in the same directory as this file. It should setup the remainder of the environment, and build the tools if necessary. Please also refer to the 'BuildNotes.txt' file for more information on building under Windows. === Unix-like operating systems === To build on Unix-like operating systems, you only need to type 'make' in the base directory of the project. === Ubuntu Notes === On Ubuntu, the following command should install all the necessary build packages to build all the C BaseTools: sudo apt-get install build-essential uuid-dev === Python sqlite3 module === On Windows, the cx_freeze will not copy the sqlite3.dll to the frozen binary directory (the same directory as build.exe and GenFds.exe). Please copy it manually from <PythonHome>\DLLs. The Python distributed with most recent Linux will have sqlite3 module built in. If not, please install sqlit3 package separately. 26-OCT-2011
