* BaseTools: Move GccLto Files to BaseToolsOliver Smith-Denny2024-07-234-76/+0
| | | | | | | | | This moves the GccLto files from ArmPkg to BaseTools as they are files that are only used in the build. This removes an artificial dependency on ArmPkg from BaseTools and keeps build related files in BaseTools. Signed-off-by: Oliver Smith-Denny <osde@linux.microsoft.com>
* ArmPkg/GccLto AARCH64: Add BTI note to LTO helper libraryArd Biesheuvel2023-03-301-0/+0
| | | | | | | | | | | | | The GccLto helper library does not contain any code, as its only purpose is to pull in other libraries that implement intrinsics to which the linker's codegen pass may emit calls. So mark it as BTI compatible, so that the linker does not complain about unannotated objects.

* ArmPkg: convert LFs to CRLF, expand hard TABsLaszlo Ersek2020-03-042-76/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We're going to switch the internal line terminators globally to LF at some point, but until then, let's use CRLF consistently. Convert source files with LFs in them to CRLF, using "unix2dos". "git show -b" prints no code changes for this patch. (I collected all the file name suffixes in this package, with: $ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev I eliminated those suffixes that didn't stand for text files, then blanket-converted the rest with unix2dos. Finally, picked up the actual changes with git-add.) At the same time, the following three files had to undergo TAB expansion: ArmPkg/Library/ArmSoftFloatLib/ArmSoftFloatLib.c ArmPkg/Library/GccLto/liblto-aarch64.s ArmPkg/Library/GccLto/liblto-arm.s I used "expand -t 2", in order to stay close to the edk2 coding style (which uses two spaces for indentation.) Both the CRLF conversion and the TAB expansion are motivated by "PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion and TAB expansion have to happen in the same patch.

* ArmPkg: add prebuilt glue binaries for GCC5 LTO supportArd Biesheuvel2016-08-024-0/+88
GCC in LTO mode interoperates poorly with non-standard libraries that provide implementations of compiler intrinsics such as memcpy/memset or the stack protector entry points. Such libraries need to be built in non-LTO mode, and then referenced explicitly on the linker command line using a -plugin-opt=-pass-through=-lxxx linker option. However, if these intrinsics are also referenced directly, the LTO version of the code will be pulled in, and will happily satisfy all other references to the same symbol. So add a pair of glue libraries, for ARM and AARCH64, that reference the known intrinsics. Since the binaries live under ArmPkg directly, we can reference them in tools_def.txt. Under LD garbage collection, the object itself will be pruned, and so will the intrinsics that end up unused by the module.
