* Modify Android mem* routines with CodeAurora versions.Pat Galizia2011-02-251-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | Update the memcpy, memmove, and memset routines to use the versions from CodeAurora when specified in the bionic/Android.mk file (actually activated in the BoardConfig.mk file under device/<vendor>/<board>). With this change, the mem* routines are only used for the msm8660, while other platforms will use the current Android mem* routines. Future platforms can modify the makefile to use the CodeAurora-based mem* routines as desired. This has the benefit of making the CodeAurora- based routines opt-in instead of opt-out. Also, PLDSIZE and PLDOFFS can be specified in the BoardConfig.mk as well, so other platforms with different PLD tunings can use the same code without modifying the source file itself. Tests with FileCycler-0.3 showed a slight 1.1% improvement with these files on an 8660v2, based on the average of three FileCycler runs with and without the patch. Since the min/max values did not overlap, and the average score showed an improvement, we can consider upstreaming these modifications. Change-Id: I5607fe6f116f8fd2b2bd5ade151778eb0d5a3663

* Remove compiler warnings when building Bionic.David 'Digit' Turner2010-06-221-1/+0

* Allow static C++ destructors to be properly called on dlclose().David 'Digit' Turner2010-06-181-6/+16
| | | | | | | | | | | | | | | | | | | | | | | With this patch, _and_ an upcoming build/ patch, the destruction of static C++ objects contained in shared libraries will happen properly when dlclose() is called. Note that this change introduces crtbegin_so.S and crtend_so.S which are currently ignored by the build system. + move definition of __dso_handle to the right place (before that, all shared libraries used the __dso_handle global variable from the C library). Note that we keep a 'weak' __dso_handle in aeabi.c to avoid breaking the build until the next patch to build/core/combo/ appears. We will be able to remove that later. + move bionic/aeabi.c to arch-arm/bionic/ (its proper location) Change-Id: Ie771aa204e3acbdf02fd30ebd4150373a1398f39 NOTE: The NDK will need to be modified to enable this feature in the shared libraries that are generated through it.

| * Set SA_RESTORER in sigaction()Matt Fischer2010-05-121-0/+2
| | | | | | | | | | | | | | | | | | GDB looks for specific opcode sequences when trying to recognize a stack frame as a signal trampoline. The sequences it looks for happen to be those created when SA_RESTORER is set, since glibc always sets a restorer. This patch does the same here, so that the trampolines can be correctly identified.

|/ | | | | | | | | | For performance reasons, we don't call the kernel helper. Instead, we directly access the TLS register on ARMv6 and higher. For ARMv5TE, keep using the hard-coded address populated by the kernel on each task switch. NOTE: Since we don't call the kernel helper, this must precisely match your kernel configuration. This is controlled by setting the ARCH_ARM_HAVE_TLS_REGISTER variable to 'true' in your board configuration file.
