Revert "Enable lld for windows"

2019-04-03T00:59:14+00:00

This reverts commit 3c21c0b1d9bab0d51100ca03aa157a1d8545c2ea.

Reason for revert: appears to break AdbWinUsb.dll usage by fastboot (and adb?)

Include libprofile-extras to all coverage variants

2019-03-29T15:56:42+00:00

Bug: http://b/128524141

Include libprofile-extras (defined in system/extras/toolchain-extras) to
all modules that need a coverage variant.  Also add
'-uinit_profile_extras' when linking with coverage.  This causes the
setup code in libprofile-extras to be linked into binaries/libraries
with coverage enabled.

We add the static library to the non-coverage variants as well but is a
no-op for them (since the '-u...' flag is not added for them).

Adding this dependency creates several circular dependencies since
coverage variants were being created for other module types that never
had any compilation or linking done during the build.  This change stops
creating coverage variants for toolchain_library, cc_prebuilt_library_*,
cc_library_headers module types (by adding a function to the linker
interface to specify whether native coverage is enabled).

Soong: Add synopsis to several modules under cc package.

2019-03-25T14:21:29+00:00

Added synopsis to the following modules under cc package:
    * cc_binary
    * cc_binary_host
    * cc_defaults
    * cc_genrule
    * cc_test
    * cc_test_host

Bug: b/128337482
Test: Generated the documentation and verified that the
synopsis was added to each of the module.

Enable lld for windows

2019-03-20T21:07:47+00:00

Bug: http://b/110800681

The following flags that the binutils linkers support are not available
in lld for Windows:
  -soname
  --no-undefined
  -rpath

Windows also uses "import libraries", which are stub libraries used only
for linking.  The binutils linkers accepted a DLL and treated them as an
import library.  But lld issues the following error:

  lld-link: error: ...DLL: bad file type. Did you specify a DLL instead
  of an import library?

To resolve this, pass '-out-implib=libFoo.a' to lld when linking
libFoo.dll.  Add libFoo.a as an implicit output to the 'ld' build rule.

Rewrite the shared libraries for a library/binary to use the import
library instead of the DLL.  As a side-effect, this also (correctly)
uses the AdbWinApi.a that's alongside
development/host/windows/prebuilt/usb/AdbWinApi.dll

Test: Run Windows tests (go/android-llvm-windows-testing) and check
absence of regressions.

Create symlink for bionic files

2019-03-14T18:04:52+00:00

This change creates following symlinks for bionic files.

/system/lib/libc.so -> /apex/com.android.runtime/lib/bionic/libc.so
/system/lib/libm.so -> /apex/com.android.runtime/lib/bionic/libm.so
/system/lib/libdl.so -> /apex/com.android.runtime/lib/bionic/libdl.so
/system/bin/linker -> /apex/com.android.runtime/bin/linker
...

This allows us to not have mountpoints under /bionic.

Bug: 125549215
Test: m and inspect the symlinks in the system partition.

If the bootstrap property is set to true, a binary configured to refer
to the bootstrap linker at /system/bin/bootstrap/linker[64]. This is for
very early processes that are executed before the init makes the linker
