Valgrind was crashing systematically on Android 4.1. This crash is caused by AT_IGNORE-ing AT_BASE. This AT_IGNORE was needed to have breakpoints in shared libs be handled properly (not very clear what is the problem in the interaction between Valgrind GDBSERVER, AT_BASE and GDB). Waiting to better understand all this, as a temporary bypass, this patch ensures we do not ignore the AT_BASE on android. The possible consequence is that breakpoints might be inserted by the Valgrind gdbserver at wrong addresses in shared lib. (any feedback on that is welcome). Valgrind was build and then "proved" to work on Android emulator 4.0 and emulator 4.1, by using memcheck on one executable. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@12758

# Start your android emulator (it takes some time).
|
|
# You can use adb shell to get a shell on the device
|
|
# and see it is working. Note that I usually get
|
|
# one or two time out from adb shell before it works

adb shell

|
|
# Once the emulator is ready, push your Valgrind to the emulator:
|
|
adb push Inst /

|
|
|
|
|
# if you need to debug:
|
|
# You have on the android side a gdbserver
|
|
# on the device side:
