[libc] Normalize LIBC_TARGET_MACHINE

2021-05-05T15:52:42+00:00

Current implementation defines LIBC_TARGET_MACHINE with the use of CMAKE_SYSTEM_PROCESSOR.
Unfortunately CMAKE_SYSTEM_PROCESSOR is OS dependent and can produce different results.
An evidence of this is the various matchers used to detect whether the architecture is x86.

This patch normalizes LIBC_TARGET_MACHINE and renames it LIBC_TARGET_ARCHITECTURE.
I've added many architectures but we may want to limit ourselves to x86 and ARM.

[libc] Setup TLS in x86_64 loader.

2020-08-08T06:19:03+00:00

The new code added is still very x86_64 specific. AArch64 support will
be added very soon and refactoring of the loader code will be done as
part of the patches adding it.

[libc] Skip entrypoints not present in the entrypoints list.

2020-06-09T21:40:28+00:00

Summary:
If a test depends on a skipped entrypoint, then the test is also
skipped. This setup will be useful as we gradually add support for
more operating systems and target architectures.

[libc][Take 2] Propagate entrypoint deps to downstream targets.

2020-04-21T17:29:09+00:00

This reverts commit a8086ba4ac85152d8407630e56e9ee5c8b46a214.
Setting couple of target properties to an empty string was missed in the
previous commit.

[libc] Revert "Propagate entrypoint deps to downstream targets."

This reverts commit 20cb440ea210597bf223505604bb5f2220a067c6 as the
target llvmlibc seems to be failing on the bots.

[libc] Propagate entrypoint deps to downstream targets.

2020-04-21T16:58:55+00:00

Deps are recrusively evaluated at the place they are needed. With this
change, one does not have to list recursive deps of entrypoints when
listing test targets. One will still have to explicitly list all
entrypoint objects when setting up an "add_entrypoint_library" target.

[libc] Add fully-qualified target names.

2020-04-11T01:01:52+00:00

Only targets setup by the special LLVM libc rules now have fully
qualified names. The naming style is similar to fully qualified names in
Python.

2020-04-08T17:18:37+00:00

Summary:
Made all header files consistent based of this documentation: https://llvm.org/docs/CodingStandards.html#file-headers.
And did the same for all source files top of file comments.

[libc] Add a simple x86_64 linux loader.

2020-03-25T17:12:35+00:00

This adds a very simple loader. This will be extended to a full loader
in future patches. A utility rule to add unittests has been added to
serve us while we are building out the full loader.
