1dd9efc541 Merge "Use mmap to read an initial ELF header of library" 2012-05-25 15:11:35 -07:00
Ji-Hwan Lee
75917c84d1 Use mmap to read an initial ELF header of library 
Also, fixes SIGSEV during calculation of si->phdr in load_library(),
which is caused by accessing PHDR area, which is not guaranteed to be
loaded.

Note that this usually does not happen because program header area is
covered by immediately following PT_LOAD entry.  But it does not hold
always.

dcbc3787bf Make the linker relocatable. 
Previously, the linker always loaded itself into the same
location in memory, which inhibited the effectiveness of Android's
ASLR implementation. Modify the linker code so it can be relocatable
and link itself at runtime.

e742c1f564 linker: set LOCAL_NO_CRT := true 
Use LOCAL_NO_CRT to prevent linking against crtbegin.o, rather than
messing with build rules. This also prevents linking against crtend.o,
which isn't needed for the linker.

077891b199 linker: Fix the computation of si->base 
The computation of si->base assumed that the first entry in the
program header table is a PT_PHDR. This results in the dynamic
linker crashing with a SIGSEGV/MAPERR when trying to load some
of the NDK unit test programs, which happen to have an EXIDX
header first, followed byu a PHDR one.

This patch fixes the computation by parsing the program header
table, looking explicitely for the PHDR entry. This fixes the
load of the NDK unit test programs, and doesn't affect system
libraries.

6cdefd06c0 Add linker support for PIE 
Modify the dynamic linker so that executables can be loaded
at locations other than 0x00000000.

Modify crtbegin* so that non-PIC compilant "thumb interwork
veneers" are not created by the linker.

08e72d0161 bionic: add support for non-NEON memcpy() on NEON SoCs 
Some SoCs that support NEON nevertheless perform better with a non-NEON than a
NEON memcpy().  This patch adds build variable ARCH_ARM_USE_NON_NEON_MEMCPY,
which can be set in BoardConfig.mk.  When ARCH_ARM_USE_NON_NEON_MEMCPY is
defined, we compile in the non-NEON optimized memcpy() even if the SoC supports
NEON.
