This is a customized gcc-4.3.1 for the Android platform. It is based on the
FSF gcc-4.3.1 release with the following modification listed in reversed
chronological order.
2009-04-21 Doug Kwan <dougkwan@google.com>
Patch arm.md for gcc bug 40153.
http://gcc.gnu.org/viewcvs?view=rev&revision=147613
Changed File:
gcc/config/arm/arm.md
2009-04-02 Doug Kwan <dougkwan@google.com>
Bring 4.3.1 to the same set of patches as 4.2.1 and shave
1 instruction off aeabi_lmul.
Changed Files:
gcc/config/arm/eabi.h: Add -Bdynamic in linker spec.
Make "-fno-exceptions -fpic -fno-short-enums -mthumb-interwork"
default C flags.
gcc/config/arm/eabi.opt: Allow -mno-android.
gcc/config/arm/t-arm-elf: Add -mthumb-interwork and -mandroid
multilib options.
gcc/doc/invoke.texi: Document -mandroid.
gcc/gcc.c: Remove automatic -mandroid.
gcc/tree-ssa-structalias.c: Fix qsort instability.
gcc/lib1funcs.asm: Reduce one instruction from aeabi_lmul
and also handle cases for THUMB2 and older ARMs.
2009-02-20 Doug Kwan <dougkwan@google.com>
Use -mandroid by default for arm-eabi.
Changed Files:
gcc/gcc.c
2009-02-16 Doug Kwan <dougkwan@google.com>
Port 2 patches from gcc-patches mailing list to fix NEON breakage.
http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00085.html
http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00134.html
Changed Files:
gcc/config/arm/arm.c
2008-07-14 Doug Kwan <dougkwan@google.com>
Port this patch from gcc-patches mailing list.
http://gcc.gnu.org/ml/gcc-patches/2008-07/msg01051.html
to implement Android specific behaviours in gcc, controllable
using a single -mandroid option of the arm*-*-eabi* targets.
The -mandroid option controls:
- names of startfile and endfile.
- list of standard C libraries (libc and, for dynamic
executables, libdl)
- name of run-time linker (/system/bin/linker)
- Default C option (-fno-excetpions)
- Default C++ option (-fno-rtti)
- Standand define (__ANDROID__)
- Low level linker flags for -shared, -dynamic, -static and -rdynamic.
Changed Files:
gcc/config.gcc
gcc/config/arm/bpabi.h
gcc/config/arm/eabi.h
gcc/config/arm/eabi.opt
gcc/config/arm/elf.h
gcc/config/arm/unknown-elf.h
2008-07-01 Doug Kwan <dougkwan@google.com>
Port __aeabi_umul optimization patch from trunk.
http://gcc.gnu.org/ml/gcc-patches/2008-07/msg00057.html
The patch implements __aeabi_lmul in hand-optimized ARM assembly.
Changed file:
gcc/config/arm/lib1funcs.asm
gcc/config/arm/t-arm-coff
gcc/config/arm/t-arm-elf
gcc/config/arm/t-linux
gcc/config/arm/t-pe
gcc/config/arm/t-strongarm-elf
gcc/config/arm/t-symbian
gcc/config/arm/t-vxworks
gcc/config/arm/t-wince-pe
2008-06-22 Doug Kwan <dougkwan@google.com>
Back-port clz optimization patch
http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00799.html
from trunk. This is similar to the clz optimization patch in Android
gcc-4.2.1 but the patch has been modified by one of the ARM port
maintainers. The back-ported patch has been slightly modified due to
difference between gcc-4.3.1 and trunk.
2008-06-21 Doug Kwan <dougkwan@google.com>
Fix code generation bug when both -fPIC and -fstack-fstack-protector
are given. The is an associated gcc bug 36480 but the problem is
still not resolved in trunk.
Changed file:
gcc/config/arm/arm.c
2008-06-20 Doug Kwan <dougkwan@google.com>
Apply the second patch in
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01577.html
to fix ICE in register renamer.
Changed file:
gcc/regrename.c
2008-06-20 Doug Kwan <dougkwan@google.com>
Apply part of the fix in bug 37156.
Changed file:
gcc/pretty-print.c
