* | Wrap ARM abort() to improve stack trace.Andy McFadden2009-10-211-0/+31
|/ | | | | | | | | | | | | | The code generated for Thumb and Thumb2 targets has different handling for abort(). Because abort() is "noreturn", it doesn't need to preserve the callee-save registers. The Thumb2 version trashes LR and makes it impossible to figure out who called abort(). This inserts a trivial stub function; net effect is stack traces are reasonable after an abort(). For bug 2191452. Eclair branch Dr. No approved by: hiroshi

* fix [2170898] abort() doesn't print a stack tarceMathias Agopian2009-10-061-2/+0
| | | | | | | the issue here is that abort() can be called from anywhere, in particular from malloc or free. When we try to use the debug_log functions, these can end up calling into some code (like malloc/free) that called abort() in the first place and end up in an infinite recursion loop.
* Re-enable ARMv7 memcpy implementation.David 'Digit' Turner2009-10-051-15/+1

| | | | | | | This is required to work-around some corny bugs in ARMv7 emulation. The emulation itself is required to run the dex pre-optimization pass for -user builds.

| * bionic/linker: fix symbol lookup during relocationsIliyan Malchev2009-09-271-26/+74
| | | | | | | | | | | | | | | | | | When resolving relocations while loading a library, the linker used to find symbols by looking them up in the list of all linked libraries for the current process, as opposed to following just the library's DT_NEEDED entries. This can cause a problem where the symbol is picked up from the wrong library. Signed-off-by: Iliyan Malchev <malchev@google.com>

* | Fix TLS access for ARMv6 and beyond.David 'Digit' Turner2009-09-223-2/+22
|/ | | | | | | | | | 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.

| * Fix an infinite loop in time2sub.David 'Digit' Turner2009-09-091-12/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that time_t is signed, and the original code relied on the fact that (X + c < X) in case of overflow for c >= 0. Unfortunately, this condition is only guaranteed by the standard for unsigned arithmetic, and the gcc 4.4.0 optimizer did completely remove the corresponding test from the code. This resulted in a missing boundary check, and an infinite loop. The problem is solved by testing explicitely for TIME_T_MIN and TIME_T_MAX in the loop that uses this. Also fix increment_overflow and long_increment_overflow which were buggy for exactly the same reasons. Note: a similar fix is needed for system/core/libcutils
