18## Common build system definitions.  Mostly standard
19## commands for building various types of targets, which
20## are used by others to construct the final targets.

29# The short names of all of the targets in the system.
30# For each element of ALL_MODULES, two other variables
31# are defined:
32#   $(ALL_MODULES.$(target)).BUILT
33#   $(ALL_MODULES.$(target)).INSTALLED
34# The BUILT variable contains LOCAL_BUILT_MODULE for that
35# target, and the INSTALLED variable contains the LOCAL_INSTALLED_MODULE.
36# Some targets may have multiple files listed in the BUILT and INSTALLED
37# sub-variables.

48ALL_MODULE_TAGS:=

51# of all targets for a particular tag.  The top-level variable
52# won't have the list of tags;  ust ALL_MODULE_TAGS to get

55# its sub-variables.)

1534## Commands for linking a static executable. In practice,
1535## we only use this on arm, so the other platforms don't
1536## have transform-o-to-static-executable defined.
1537## Clang driver needs -static to create static executable.
1538## However, bionic/linker uses -shared to overwrite.
1539## Linker for x86 targets does not allow coexistance of -static and -shared,
1540## so we add -static only if -shared is not used.
