Please re-open this bug. I'm affected by it with GCC 4.8.3, when I build static
ARMv7 binaries against musl 1.0.4.

> Some MacPorts users are now reporting this.

Can you provide a backtrace of the error? In the build directory, run the
executable "gcc/cc1" on a test source file (like the empty main program that
libgcc configure tries to compile), under the debugger: "lldb -- ./gcc/cc1
test.c"

The debugger starts, then you type "r" (without quotes) and enter. It will stop
at the point of failure, then you type "bt" and enter again. Paste here the
result of that last command. This will help understand where things are going
wrong.

--- Comment #8 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I've reproduced this with a cross-compiler targeting powerpc-apple-darwin9: the
cc1 built fails at startup, with any source file, as shown above.

Then bisection shows this 4.9.2 regression is due to revision 213597:

2014-08-04  Rohit  <rohitarulraj@freescale.com>

          (rs6000_dwarf_register_span) : For SPE high registers, replace
          dwarf register numbers with GCC hard register numbers.
          (rs6000_init_dwarf_reg_sizes_extra) : Likewise.
          (rs6000_dbx_register_number): For SPE high registers, return dwarf
          register number for the corresponding GCC hard register number.

        * config/rs6000/rs6000.h
          (FIRST_PSEUDO_REGISTER) : Update based on 32 newly added GCC hard
          register numbers for SPE high registers.
          (DWARF_FRAME_REGISTERS) :  Likewise.
          (DWARF_REG_TO_UNWIND_COLUMN) : Likewise.
          (DWARF_FRAME_REGNUM) : Likewise.
          (FIXED_REGISTERS) : Likewise.

          (REG_CLASS_CONTENTS) : Likewise.
          (SPE_HIGH_REGNO_P) : New macro to identify SPE high registers.


I looked into reginfo.c: array initial_reg_names has 117 elements:

static const char *const initial_reg_names[] = { "r0", "r1", "r2", "r3", "r4",
"r5", "r6", "r7", "r8", "r9", "r10", "r11", "r12", "r13", "r14", "r15", "r16",
"r17", "r18", "r19", "r20", "r21", "r22", "r23", "r24", "r25", "r26", "r27",
"r28", "r29", "r30", "r31", "f0", "f1", "f2", "f3", "f4", "f5", "f6", "f7",
"f8", "f9", "f10", "f11", "f12", "f13", "f14", "f15", "f16", "f17", "f18",
"f19", "f20", "f21", "f22", "f23", "f24", "f25", "f26", "f27", "f28", "f29",
"f30", "f31", "mq", "lr", "ctr", "ap", "cr0", "cr1", "cr2", "cr3", "cr4",
"cr5", "cr6", "cr7", "xer", "v0", "v1", "v2", "v3", "v4", "v5", "v6", "v7",

"v30", "v31", "vrsave", "vscr", "spe_acc", "spefscr", "sfp", "tfhar", "tfiar",
"texasr" };

while reg_names (this_target_hard_regs->x_reg_names) has size
FIRST_PSEUDO_REGISTER, which equals 149.

This also affects trunk, rendering the compiler unusable and breaking
bootstrap.

sorry I fixed this months ago locally..
 I will push a patch to fix ASAP.

note that there are 4 bootstrap breakers on PPC (trunk)
1. this
2. libcc1 (same fail as x86)
3. libiberty needs some options massage to build PIC properly (will also break
i686-darwin*)
4. libada is currently looking for __environ and needs a modification to the
makefile, affects at least 10.5, 10.6

More annoying, I think, is that this one is also on 4.9, and actually made it
into the 4.9.2 release.

In this case you could test just by building a cc1 for powerpc-apple-darwin9 X
from whatever host you're using - I think that should not take more than
20mins.

cc1 builds for powerpc-apple-darwin9 without any issues with the attached
patch.
But the reported issue was observed while building libgcc.

The change to add those registers is not on 4.8 branch - this fix isn;t needed
there (so far).

FYI, you can use -fcompare-debug here. Various dump functions (e.g.
-fdump-tree-optimized, -fdump-rtl-expand, etc) will be dumped in two versions,
the "debug" version will be suffixed with .gk.
