Enabling sysroot support in libtool exposed a bug where the final
library had an RPATH encoded into it which still pointed to the
sysroot. This works around the issue until it gets sorted out
upstream.
Fix suggested by Richard Purdie <richard.purdie@linuxfoundation.org>

The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
This target doesn't really have a 128-bit integer type, however it does use
TImode to represent the return value of certain special ABI defined library
functions. This results in type_for_size(TImode) being called.
Because TImode deosn't correspond to any gfortran integer kind
gfc_type_for_size returns NULL and we segfault shortly after.
The patch below fixes this by making gfc_type_for_size handle TImode in the
same way as the C frontend.
Tested on x86_64-linux and arm-linux-gnueabi.
Applied to trunk.

Upstream-Status: Inappropriate [embedded specific]
GCC has internal multilib handling code but it assumes a very specific rigid directory
layout. The build system implementation of multilib layout is very generic and allows
complete customisation of the library directories.
This patch is a partial solution to allow any custom directories to be passed into gcc
and handled correctly. It forces gcc to use the base_libdir (which is the current
directory, "."). We need to do this for each multilib that is configured as we don't
know which compiler options may be being passed into the compiler. Since we have a compiler
per mulitlib at this point that isn't an issue.
The one problem is the target compiler is only going to work for the default multlilib at
this point. Ideally we'd figure out which multilibs were being enabled with which paths
and be able to patch these entries with a complete set of correct paths but this we
don't have such code at this point. This is something the target gcc recipe should do
and override these platform defaults in its build config.

Hi,
The attached patch makes sure that we create smaller object code for
simple switch statements. We just make sure to flatten the switch
statement into an if-else chain, basically.
This fixes a size-regression as compared to gcc-3.4, as can be seen
below.
2007-04-15 Bernhard Fischer <..>
* stmt.c (expand_case): Do not create a complex binary tree when
optimizing for size but rather use the simple ordered list.
(emit_case_nodes): do not emit jumps to the default_label when
optimizing for size.
Not regtested so far.
Comments?
Attached is the test switch.c mentioned below.

Upstream-Status: Submitted
ChangeLog
* Makefile.in (gcc_gxx_include_dir_add_sysroot): New.
(PREPROCESSOR_DEFINES): Define GPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT.
* cppdefault.c (cpp_include_defaults): replace hard coded "1" with
GPLUSPLUS_INCLUDE_DIR_ADD_SYSROOT for "add_sysroot" field.
* configure.ac (AC_SUBST): Add gcc_gxx_include_dir_add_sysroot to
control whether sysroot should be prepended to gxx include dir.
* configure: Regenerate.
Hi, this is a follow up for issue "http://codereview.appspot.com/4641076".
The rationale for the patch copied from previous thread:
=======================================
The setup:
Configuring a toolchain targeting x86-64 GNU Linux (Ubuntu Lucid), as a
cross-compiler. Using a sysroot to provide the Lucid headers+libraries,
with the sysroot path being within the GCC install tree. Want to use the
Lucid system libstdc++ and headers, which means that I'm not
building/installing libstdc++-v3.
So, configuring with:
--with-sysroot="$SYSROOT"
--disable-libstdc++-v3 \
--with-gxx-include-dir="$SYSROOT/usr/include/c++/4.4" \
(among other options).
Hoping to support two usage models with this configuration, w.r.t. use of
the sysroot:
(1) somebody installs the sysroot in the normal location relative to the
GCC install, and relocates the whole bundle (sysroot+GCC). This works
great AFAICT, GCC finds its includes (including the C++ includes) thanks
to the add_standard_paths iprefix handling.
(2) somebody installs the sysroot in a non-standard location, and uses
--sysroot to try to access it. This works fine for the C headers, but
doesn't work.
For the C headers, add_standard_paths prepends the sysroot location to
the /usr/include path (since that's what's specified in cppdefault.c for
that path). It doesn't do the same for the C++ include path, though
(again, as specified in cppdefault.c).
add_standard_paths doesn't attempt to relocate built-in include paths that
start with the compiled-in sysroot location (e.g., the g++ include dir, in
this case). This isn't surprising really: normally you either prepend the
sysroot location or you don't (as specified by cppdefault.c); none of the
built-in paths normally *start* with the sysroot location and need to be
relocated. However, in this odd-ball case of trying to use the C++ headers
from the sysroot, one of the paths *does* need to be relocated in this way.

GCC: disable MASK_RELAX_PIC_CALLS bit
The new feature added after 4.3.3
"http://www.pubbs.net/200909/gcc/94048-patch-add-support-for-rmipsjalr.html"
will cause cc1plus eat up all the system memory when build webkit-gtk.
The function mips_get_pic_call_symbol keeps on recursively calling itself.
Disable this feature to walk aside the bug.

Hi,
This patch fixes the issue in the (Launchpad, not GCC) bug tracker:
https://bugs.launchpad.net/gcc-linaro/+bug/675347
The problem was introduced by the patch from DJ to honour volatile
bitfield types:
http://gcc.gnu.org/ml/gcc-patches/2010-06/msg01167.html
but not exposed (on ARM) until the option was made the default (on the
Linaro branch) -- it's not yet the default on mainline.
The issue is as follows: after DJ's patch and with
-fstrict-volatile-bitfields, in expr.c:expand_expr_real_1, the if
condition with the comment "In cases where an aligned union has an
unaligned object as a field, we might be extracting a BLKmode value
from an integer-mode (e.g., SImode) object [...]" triggers for a normal
(non-bitfield) volatile field of a struct/class.
But, this appears to be over-eager: in the particular case mentioned
above, when expanding a "volatile int" struct field used as a memory
constraint for an inline asm, we end up with something which is no
longer addressable (I think because of the actions of
extract_bit_field). So, compilation aborts.
My proposed fix is to restrict the conditional by only making it execute
for -fstrict-volatile-bitfields only for non-naturally-aligned accesses:
this appears to work (fixes test in question, and no regressions for
cross to ARM Linux, gcc/g++/libstdc++, with -fstrict-volatile-bitfields
turned on), but I don't know if there will be unintended consequences.
DJ, does it look sane to you?
Incidentally the constraints in the inline asm in the Launchpad
testcase might be slightly dubious (attempting to force (mem (reg)) by
using both "+m" (var) and "r" (&var) constraints), but replacing
them with e.g.:
asm volatile("0:\n"
"ldrex %[newValue], %[_q_value]\n"
"sub %[newValue], %[newValue], #1\n"
"strex %[result], %[newValue], %[_q_value]\n"
"teq %[result], #0\n"
"bne 0b\n"
: [newValue] "=&r" (newValue),
[result] "=&r" (result)
: [_q_value] "Q" (_q_value)
: "cc", "memory");
still leads to a warning (not an error) with trunk and
-fstrict-volatile-bitfields:
atomic-changed.cc:24:35: warning: use of memory input without lvalue in
asm operand 2 is deprecated [enabled by default]
The warning goes away with the attached patch. So, I don't think the
problem is purely that the original inline asm is invalid.
OK to apply, or any comments?

* expr.c (expand_expr_real_1): Only use BLKmode for volatile
accesses which are not naturally aligned.

The LINK_SPEC for linux gets overwritten by linux-eabi.h which
means the value of TARGET_FIX_V4BX_SPEC gets lost and as a result
the option is not passed to linker when chosing march=armv4
This patch redefines this in linux-eabi.h and reinserts it
for eabi defaulting toolchains.
We might want to send it upstream

Hi,
The attached patch fixes Bugzilla 45847
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45847). When compiling
without -mvectorize-with-neon-quad and vectorizing scalar widening
operations that widen words to double words, there are no corresponding
vector types for DI scalar types. For this scenario, a call to
get_vect_type_for_scalar_type() returns NULL and an absent NULL-check
caused this segfault. The attached patch adds this NULL-check. Also,
this is consistent with all the other places where a NULL-check follows
a call to get_vect_type_for_scalar_type() in tree-vect-patterns.c.
Regression tested with arm-linux-gnueabi. OK?
