BaseTools: Fix CLANGDWARF LoongArch64 ASLC build

2026-10-26T11:57:25+00:00

When building a module containing .aslc files on the CLANGDWARF LoongArch64 platform, errors occur because the target and linker are set incorrectly. Therefore, this patch: - Add the missing target triplet to ASLCC_FLAGS so ACPI objects are compiled for LoongArch64 rather than the host architecture. - Add -fuse-ld=lld to ASLDLINK_FLAGS so linking does not fall back to the GCC ld, which lacks elf64loongarch support.

BaseTools: FMMT: Add replacement regression tests

2026-10-22T01:36:43+00:00

This change adds a few unit test cases to validate the FMMT tool. Signed-off-by: Kun Qin

BaseTools: FvHandler: Safely update FV free-space nodes

2026-10-22T01:36:43+00:00

Current FV resize routine assumes that the final child is always a free- space node. However, when no such node exists, these routines can remove or overwrite valid trailing FFS nodes. One replacement path also inserts the free-space byte count instead of the constructed tree node. This change centralizes free-space node creation, resizing, and removal, using the helper for direct replacements and recursive parent resizing. Signed-off-by: Kun Qin

BaseTools: FMMTOperation: Use distinct FFS trees for repeated replacement

2026-10-22T01:36:43+00:00

Current `ReplaceFfs` reuses the parsed replacement FFS tree for every matching target. However, `FvHandler` mutates the tree while attaching it to a target, causing later replacements inherit state from an earlier replaced instance and hang the process. This change uses deep-copy of the replacement tree for each target to avoid the failure case. Signed-off-by: Kun Qin

BaseTools/Plugin/HostBasedUnitTestRunner: Skip empty architectures

2026-10-21T00:41:20+00:00

The host unit test runner returns success when an architecture has no test executables. This skips later architectures and can hide earlier test or coverage failures. Continue to the next architecture instead and include the architecture in the warning. Preserve the accumulated failure count. Signed-off-by: Bosco Chen (AMI US Holdings Inc)

BaseTools: Reject trailing content after !else and !endif

2026-10-08T03:58:55+00:00

The DSC parser accepts "!else if " as an unconditional !else branch without evaluating the trailing condition. This can select an unintended build branch instead of reporting the syntax error. For example, the following incorrect syntax is currently accepted: !if $(MODE) == 1 # Branch A !else if $(MODE) == 2 # Branch B !endif When MODE is 3, the parser treats the second directive as a plain !else and selects branch B. Replacing it with "!elseif $(MODE) == 2" would correctly select neither branch. Reject trailing content after !else and !endif. When the first word following !else is "if", suggest "!elseif " instead. Trailing comments remain valid because they are removed before directive parsing. Cc: Fei Shen Signed-off-by: Dongyan Qian

BaseTools/FMMT: Return non-zero exit status on failure

2026-09-29T17:12:07+00:00

FMMT catches exceptions from operations such as viewing a missing input file, prints the error, and then returns status 0. Callers and scripts treat that as success. Set status to 1 in the exception handler so the process exit code matches the failure. A regression test covers FMMT -v not-a-file. Signed-off-by: Zhaoqi Xu

BaseTools: WindowsVsToolChain: Filter vs vars on specific vc

2026-09-28T21:19:11+00:00

Filters the extra vs vars gathered via QueryVcVariables() to specifically be the ones associated with the vc version set in the same plugin. This is to prevent the version compiler version differenting from the version of any included .c / .h files that are made available through the vs vars such as LIB, INCLUDE, etc. Additionally logs a message when multiple vc versions are detected on the system and specifically which vc version is being used.

BaseTools: Add ClangToolChain build plugin

2026-09-17T17:11:50+00:00

Add a new edk2-pytools build plugin that automatically configures CLANG_BIN for CLANGPDB and CLANGDWARF tool chains. The plugin resolves the clang binary path by checking, in order: 1. CLANG_BIN environment variable 2. System PATH 3. Default LLVM install path (Windows) 4. VS-installed clang (Windows) The plugin also reports clang and linker (lld-link/lld) versions to the version aggregator for build logging. Signed-off-by: Aaron Pop

BaseTools/FirmwareStorageFormat: Fix FV ext entry struct factory functions

2026-09-13T19:05:51+00:00

The Refine_FV_EXT_ENTRY_OEM_TYPE_Header() and Refine_FV_EXT_ENTRY_GUID_TYPE_Header() functions incorrectly return an instantiation attempt of the local class with `Structure` as an argument (e.g., `return ClassName(Structure)`) instead of returning the class itself (e.g., `return ClassName`). This causes FMMT to fail with: "expected EFI_FIRMWARE_VOLUME_EXT_ENTRY instance, got _ctypes.PyCStructType" When processing FVs that contain ext header entries of type 0x01 (OEM Type) or type 0x02 (GUID Type, used for FV UI Name when FvNameString = TRUE). Fix by returning the class directly, matching the pattern used by Refine_FV_Header() which correctly returns the class for subsequent .from_buffer_copy() calls. Signed-off-by: Michael D Kinney
