* changes:
  Use relative paths in copygcclib.sh deps files
  Move -fno-canonical-system-headers to global cflags
2017-11-06 23:04:09 +00:00
Colin Cross 39d450b374 Move -fno-canonical-system-headers to global cflags
-fno-canonical-system-headers is required for gcc to use relative
paths to system headers in deps files, and is stripped out for
clang.  Move it to the global flags so it affects windows gcc builds.

* changes:
  Remove no_default_compiler_flags property

  Consolidate ldflags that are used on all devices
  Remove -Wl,--gc-sections from target flags

Colin Cross 87dd963ace Remove no_default_compiler_flags property
no_default_compiler_flags is only used by the crt* modules,
is unnecessary, and causes problems when necessary flags like
-no-canonical-prefixes are not passed.  Remove the property.

Use useVndk() instead of noDefaultCompilerFlags() to determine
if adding libc as a dependency is necessary and won't cause a
circular dependency.

Move all the flags that are used everywhere (or should be used
everywhere) into cc/config/global.go:
-no-canonical-prefixes
-fno-exceptions
-Wno-multichar
-O2
-g
-fno-strict-aliasing

Also remove flags that are already in noOverrideGlobalCflags:
-Werror=pointer-to-int-cast
-Werror=int-to-pointer-cast

x86 and x86_64 were specifying -fstrict-aliasing, but that was
being overriden later by -fno-strict-aliasing, so remove it.
ARM devices still override -fno-strict-aliasing to -fstrict-aliasing
when using ARM (vs. Thumb) instruction set.

Jayant Chowdhary a3bb1b3e3b Convert abi warnings to errors.
Convert abi warnings to errors by removing the -advice-only flag from
the invocation of header-abi-diff. This will only apply to branches with
reference abi dumps checked into prebuilts/abi-dumps/(v)ndk (since
abi-diffing will only be triggered on them.)

Also allow for:

1) Extensions.
2) Changes to types in exported headers, unreferenced by public symbols still
   trigger warnings.
3) Any removal of symbols appearing in a shared library's .dynsym table, but not
   in exported headers is still a warning.

Vishwath Mohan d4b484b070 Build system changes for CFI (Soong)
This CL makes multiples changes in preparation for platform-wide CFI.

(a) Adds a second -version-script=... to the command line
when building components that use a version script. This ensures that
__cfi_check is also exported, and allows CFI to be enabled for these
components.

(b) Adds both topdown and bottom up mutators for CFI to help propagate
dependencies correctly for components that may need CFI disabled.

(c) Fixes an issue with the mutators to correctly apply settings to
both generated variants

(d) Fixes issues when components have more than a single visibility
flag.

Pirama Arumuga Nainar 6aeed8b439 Add enable_profile_use property
Bug: http://b/65598278

This property defaults to 'true' and setting it to false skips profile
use.  This escape hatch lets us disable PGO for a module without
completely removing the 'pgo' property.  Additionally, this also helps
selectively disabling PGO for some architectures, if desired.

Test: Test that -fprofile-use is not added for a test module if
'enable_profile_use: false' is set.

Jiyong Park 6a43f04777 Squash vendor sources before linkageMutator runs
linkageMutator removes srcs property of the shared variant of a lib in
order to reuse *.o files compiled for the static variant also to the
shared variant.

However, this causes problem when vendor-specific srcs are specified in
target: {vendor: {srcs: ["..."]}}. For example, let's assume

cc_library {
    name: "libfoo",
    srcs: ["foo.c"],
    target: {
        vendor: {
            srcs: ["bar.c"],
        },
    },
}

Then,
static_vendor: inputs = foo.o, bar.o
shared_vendor: inputs = foo.o (from static_vendor), bar.o (from
static_vendor), bar.o

So, bar.o is included twice and this causes multiple symbol definition
error.

In order to handle the problem, vendor mutator is applied before the
linkage mutator and the vendor-specific srcs are squashed in the vendor
mutator.
