* BaseTools/tools_def CLANGDWARF: Permit text relocationsArd Biesheuvel2023-04-061-1/+1
| | | | | | | | | | | | | | | | | | | | | 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 disallowing text relocations in PIE executables, as this would require text segments to be updated at runtime, which is bad for security and increases the copy-on-write footprint of ELF executables and shared libraries. However, none of those concerns apply to PE/COFF executables in the context of EFI, which are copied into memory rather than mmap()'ed, and fixed up by the loader before launch. So pass -z notext to the LLD linker to permit runtime relocations in read-only sections. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Rebecca Cran <rebecca@bsdio.com>

| | | | | | | | | | | | | | | | The clang toolchain might default to fPIE/fPIC, which prevents lld from linking the objects into a binary. Specify -fno-pie -fno-pic as done on GCC to fix linking.

* ArmPkg, BaseTools AARCH64: Add BTI ELF note to .hii objectsArd Biesheuvel2023-03-301-2/+3
| | | | | | | | | | | | | | | | The ELF based toolchains use objcopy to create HII object files, which contain only a single .hii section. This means no GNU note is inserted that describes the object as compatible with BTI, even though the lack of executable code in such an object makes the distinction irrelevant. However, the linker will not add the note globally to the resulting ELF executable, and this breaks BTI compatibility. So let's insert a GNU BTI-compatible ELF note by hand when generating such object files.

| | | | | | | | | | | | | | | | | | | | The ebp/rbp register can either be used for the frame pointer or as general purpose register. With gcc (and clang) this depends on the -f(no-)omit-frame-pointer switch. This patch updates tools_def.template to explicitly set the compiler option and also add a define to allow conditionally compile code. The new define is used to fix stack switching in TemporaryRamMigration. The ebp/rbp must not be touched when the compiler can use it as general purpose register. With version 12 gcc starts actually using the register, so changing it leads to firmware crashes in some configurations.

The "-Wpointer-arith" allows to: "Warn about anything that depends on the "size of" a function type or of void. GNU C assigns these types a size of 1, for convenience in calculations with void * pointers and pointers to functions." This flag is available since GCC2.95.3 which came out in 2001.

* BaseTools: Compile AML bytecode arrays into .obj filePierre Gondois2020-07-021-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AmlToHex script and Posix/WindowsLike wrappers convert an AML file to a .hex file, containing a C array storing AML bytecode. This ".hex" file can then be included in a C file, allowing to access the AML bytecode from this C file. The EDK2 build system doesn't allow to a depict dependency orders between files of different languages. For instance, in a module containing a ".c" file and a ".asl", the ".c" file may or may not be built prior to the ".asl" file. This prevents any inclusion of a generated ".hex" in a ".c" file since this later ".hex" file may or may not have been created yet. This patch modifies the AmlToC script to generate a C file instead of a ".hex" file. It also adds the generation of an intermediate ".amli" file when compiling an ASL file, and adds a rule to convert this ".amli" to a C file. This allows to generate a C file containing the AML bytecode from an ASL file. This C file will then be handled by the EDK2 build system to generate an object file. Thus, no file inclusion will be required anymore. The C file requiring the AML bytecode as a C array, and the ASL file, will be compiled independently. The C array must be defined as an external symbol. The linker is resolving the reference to the C array symbol. To summarize, the flow goes as: -1. ASL file is compiled to AML; -2. AML file is copied to a ".amli" intermediate file; -3. EDK2 build system applies the rule relevant to ".amli" files. This is, calling the "AmlToC" script, generating a C file from the ".amli" file; -4. EDK2 build system applies the rule relevant to C files. This is creating an object file. -5. EDK2 build system links the object file containing the AML bytecode with the object file requiring it.

* BaseTools: Use SEH exceptions in CLANGPDB for IA32Vitaly Cheptsov2020-04-081-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2628 This patch reduces the size of IA32 binaries by ensuring that no .debug_frame / .eh_frame sections are generated through forcing SEH exception model, which is already the default in clang for X64. EDK II does not support exceptions, and in future we should disable them instead of switching to some other variant. Currently this is not possible due to the following LLVM bugs: https://bugs.llvm.org/show_bug.cgi?id=45324 https://bugs.llvm.org/show_bug.cgi?id=45325 Upon applying this patch OvmfPkgIA32.dsc compilation in DEBUG mode gets the following size decrease with clang 9.0.1.

| | | | | | | | | | | | | | | | | | | | BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2487 The call stack unwindability of the COFF X64 binary requires the binary to remain the pdata and xdata sections. Details see the MSVC X64 calling convertion doc in below link: https://docs.microsoft.com/en-us/cpp/build/x64-calling-convention Current build options discard or zero the data in pdata and xdata sections which cause the debugger cannot correctly unwind the X64 binary call stack in the runtime. Enhance the build options to force emit the unwind tables and keep the data of pdata and xdata sections correct in the binary.

* BaseTools: Script for converting .aml to .hexPierre Gondois2020-02-061-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | The "-tc" option of the iasl compiler allows to generate a .hex file containing a C array storing AML bytecode. An online discussion suggested that this "-tc" option was specific to the iasl compiler and it shouldn't be relied on. This conversation is available at: https://edk2.groups.io/g/devel/topic/39786201#49659 A way to address this issue is to implement a compiler independent script that takes an AML file as input, and generates a .hex file. This patch implements a Python script that converts an AML file to a .hex file, containing a C array storing AML bytecode. This scipt has been tested with the AML output from the following compilers supported by the EDKII implementation: * Intel ASL compiler * Microsoft ASL compiler Signed-off-by: Pierre Gondois <pierre.gondois@arm.com> Reviewed-by: Bob Feng <bob.c.feng@intel.com>

* BaseTools/Conf/gitattributes: fix "--function-context" for C source codeLaszlo Ersek2020-01-311-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "--function-context" ("-W") option of git-diff displays the entire body of a modified function, not just small modified hunks within the function. It is useful for reviewers when the code changes to the function are small, but they could affect, or depend on, control flow that is far away in the same function. Of course, the size of the displayed context can be controlled with the "-U" option anyway, but such fixed-size contexts are usually either too small, or too large, in the above scenario. It turns out that "--function-context" does not work correctly for C source files in edk2. In particular, labels for the goto instruction (which the edk2 coding style places in the leftmost column) appear to terminate "--function-context". The "git" utility contains built-in hunk header patterns for the C and C++ languages. However, they do not take effect in edk2 because we don't explicitly assign the "cpp" git-diff driver to our C files. The gitattributes(5) manual explains that this is required: > There are a few built-in patterns to make this easier, and > tex is one of them, so you do not have to write the above in > your configuration file (you still need to enable this with > the attribute mechanism, via .gitattributes). The following > built in patterns are available: > > [...] > > * cpp suitable for source code in the C and C++ > languages. The key statement is the one in parentheses. Grab the suffix lists from the [C-Code-File] and [Acpi-Table-Code-File] sections of "BaseTools/Conf/build_rule.template", add "*.h" and "*.H", and mark those as belonging to the "cpp" git-diff driver.
