BaseTools: GNUMakefiles must use CMD.EXE in Windows

2025-12-24T02:03:38+00:00

Use $(OS) in all GNUMakefiles to detect if the GNUMakefile is being used in a Windows OS. If a Windows OS is detected, then override SHELL to use cmd.exe. This prevents make utility from using sh.exe if sh.exe happens to be in PATH. If sh.exe is used, then backslash (\) characters in file paths are removed and builds break for files not found.

BaseTools: AutoGen: Optimize tuple creation using tuple() for PcdDbBuffer

2025-12-02T02:21:22+00:00

Replace manual loop-based tuple construction with the built-in tuple() function when converting PcdDbBuffer to a tuple. This change significantly improves performance—approximately three times faster—resulting in substantial build time savings in large environments. Previously, the code iterated over each byte in PcdDbBuffer, unpacking and appending it to a tuple. The new approach leverages tuple(PcdDbBuffer) to achieve the same result more efficiently. The generated tuple remains identical to the original implementation. TEST=The generated tuple is the same than with to original code Signed-off-by: Jeremy Compostella

BaseTools: fix various typos

2025-11-21T21:49:59+00:00

This commit is the first in a series of multiple commits to fix various typos in the code, originating mostly from copy&paste over the years. Most of them only affect documentation and not code. Signed-off-by: Philipp Schuster

BaseTools: Remove DXE_SAL_DRIVER

2025-10-30T10:00:32+00:00

The DXE_SAL_DRIVER module type was introduced to support Itanium (IPF) platforms. Since support for Itanium processors has been dropped, the instances of DXE_SAL_DRIVER have been removed. Ref: [3cb0a311cb7e747d7be5c5076d0fff76ad256d2b] Cc: Sachin Ganesh Signed-off-by: Sathya Ravichandran

BaseTools/AutoGen: GenMake response file quotes strings

2025-02-02T19:22:42+00:00

If command line options are moved into a response file of a GCC family build, then the file path separators are converted from '\' to '/'. However, this can corrupt command line options that are quoted strings. Update GenMake to no convert '\' to '/' in quoted strings. Signed-off-by: Michael D Kinney

BaseTools: Update Stack Cookie Logic

2024-09-13T03:58:46+00:00

This patch updates the GenC logic to generate a random stack cookie value for the stack check libraries. These random values improve security for modules which cannot update the global intrinsics. If the stack cookie value is randomized in the AutoGen.h file each build, the build system will determine the module/library must be rebuilt causing effectively a clean build every time. This also makes binary reproducibility impossible. This patch updates the early build scripts to create 32 and 64-bit JSON files in the build output directory which each contain 100 randomized stack cookie values for each bitwidth. If the JSON files are already present, then they are not recreated which allows them to be stored and moved to other builds for binary reproducibility. Because they are in the build directory, a clean build will cause the values to be regenerated. The logic which creates AutoGen.h will read these JSON files and use a hash of the module GUID (the hash seed is fixed in Basetools) to index into the array of stack cookie values for the module bitwidth. This model is necessary because there isn't thread-consistent data so we cannot use a locking mechanism to ensure only one thread is writing to the stack cookie files at a time. With this model, the build threads only need to read from the files. Signed-off-by: Oliver Smith-Denny

BaseTools: GenMake: FIx missing logs from GenMake.py
