We could make our warning much more useful by being silent for empty case statements, FYI, clang's warning does exactly this, i.e. it doesn't (and never did) warn on empty case labels. There's also a way to silence this warning in cases where fallthrough is intended: [[clang::fallthrough]]; construct, which uses custom C++11 statement attribute clang::fallthrough. There's a doc here: http://clang.llvm.org/docs/LanguageExtensions.html#clang__fallthrough In an ideal world, it would be great if GCC had a compatible implementation using C++11 attributes (except for a namespace of the attribute), or for example, using a built-in function. So that it was possible to have the same syntax in source code, at least using a macro. Command-line flags compatibility would also be nice. Or if you have any reasonable suggestions on how this diagnostic can be made better, I'll be glad to discuss this. and in light of other warnings starting with -Wswitch, I would recommend we name the warning -Wswitch-fall-through or something similar. If we want to have an additional warning that warns for all fall-through, as clang does, we could also add -Wswitch-empty-fall-through.

(In reply to comment #0)
Maybe a few peepholes would help here?
Sure. Peephole looks to be reasonable for this.
I've investigated a little bit regarding this issue. First I tried to beat it
with peepholes, but the actual problem is that in the load/store expanders the
predicates use the 'nonimmediate_operand' and/or 'general_operand' functions
from recog.c, which reject volatile mems, because its 'volatile_ok' var is '0'
during RTL expansion.
As a consequence, only simple single-register addressing modes are allowed for
volatile mems. Except for displacement address modes, since those have
explicit mem patterns, which would match during expansion.
In recog.c there is a comment:
/* Nonzero means allow operands to be volatile.
This should be 0 if you are generating rtl, such as if you are calling
the functions in optabs.c and expmed.c (most of the time).
This should be 1 if all valid insns need to be recognized,
such as in reginfo.c and final.c and reload.c.
init_recog and init_recog_no_volatile are responsible for setting this. */
int volatile_ok;
And in function.c:
void
expand_function_start (tree subr)
{
/* Make sure volatile mem refs aren't considered
valid operands of arithmetic insns. */
init_recog_no_volatile ();
If that is the only reason for rejecting volatile mems, then I think it would
be OK to match volatile mems in the load/store expanders for SH, since there
are no arithmetic insns that take mems anyway (except for some GBR byte mem
modification insns, which aren't used in the backend).
Kaz, does this make sense?

[Bug target/54089] [SH] Refactor shift patterns
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54089
--- Comment #18 from Oleg Endo olegendo at gcc dot gnu.org 2012-09-17
23:29:52 UTC ---
Created attachment 28207
-- http://gcc.gnu.org/bugzilla/attachment.cgi?id=28207
Arithmetic right shift rework
I have tried to apply the same strategies to the arithmetic right shift
patterns as for logical right/left shift patterns.
What happens then is that combine will see arithmetic right shift patterns (for
shift amounts 1) and will fail to convert arithmetic right shifts to logical
right shifts where it would actually be possible. This results in bigger code
since arithmetic shifts on SH are more expensive than logical shifts.
Unfortunately, combine will only do the shift type conversion if it can combine
the logical shift with some other insn -- which is not very likely on SH.
Thus, the logical shift is discarded. If however, no arithmetic shift pattern
is there that matches the shift amount (which is currently the case), combine
will split out the logical shift.
Not having arithmetic right shift patterns makes it difficult to write combine
patterns for things like ...
char test (int x)
{
return x 24;
}
which ends up as:
-m4:
mov#-24,r1
shadr1,r4
rts
exts.br4,r0
-m2:
mov.l.L3,r1
sts.lpr,@-r15
jsr@r1
nop
mov
lds.l@r15+,pr
rts
nop
.L4:
.align 2
.L3:
.long___ashiftrt_r4_24
On the other hand, the following is handled almost as expected:
unsigned char test (int a)
{
return a 24;
}
-m4:
movr4,r0
shlr16r0
rts
shlr8r0
-m2:
mov.l.L3,r1
sts.lpr,@-r15
jsr@r1
nop
extu.br4,r0
lds.l@r15+,p
rts
nop
.L4:
.align 2
.L3:
.long___ashiftrt_r4_24
According to my understanding, to fix those issues something like the attached
patch would be required. However, it would also require a separate arithmetic
right shift to logical right shift conversion pass.

Hello libiberty experts, I don't see anything saying that sha1_process_block() has a size limit on its input buffer, and if the length of the buffer is big (e.g., 2^32 on a 64-bit machine) then this code won't correctly add a 64-bit number to 64-bit number: /* First increment the byte count. RFC 1321 specifies the possible length of the file up to 2^64 bits. Here we only compute the number of bytes. Do a double word increment. */ ctx-total[0] += len; if (ctx-total[0] len) ++ctx-total[1]; The above is at sha1.c around line 302. regards, Geoff Pike

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54584 --- Comment #2 from Larry Baker baker at usgs dot gov 2012-09-18 02:44:43 UTC --- The Sourcery (Mentor Graphics) ColdFire uClinux SDK I use uses binutils-1.21. I installed binutils-2.22 and the latest uClinux elf2flt (downloaded 20120730). $ /usr/local/gcc-4.7.1/bin/m68k-uclinux-ld -V -v GNU ld (GNU Binutils) 2.22 Supported emulations: m68kelf GNU ld (GNU Binutils) 2.22 The error message is the same (Nonrepresentable section on output). I am able to issue the failing command (collect2) outside of make gcc: $ COMPILER_PATH=/tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/:/usr/local/gcc-4.7.1/m68k-uclinux/bin/:/usr/local/gcc-4.7.1/m68k-uclinux/lib/ \ /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/collect2 --sysroot=/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data --eh-frame-hdr -elf2flt -o conftest -t /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crt1.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crti.o /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtbegin.o -L/tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data -L/usr/local/gcc-4.7.1/m68k-uclinux/lib/msep-data -L/tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc -L/usr/local/gcc-4.7.1/m68k-uclinux/bin -L/usr/local/gcc-4.7.1/m68k-uclinux/lib -L/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib conftest.o -lgcc -lc -lgcc /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtend.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crtn.o /usr/local/gcc-4.7.1/m68k-uclinux/bin/ld.real: mode m68kelf /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crt1.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crti.o /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtbegin.o conftest.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)__uClibc_main.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)strrchr.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)exit.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)_exit.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)__errno_location.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)strchr.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)errno.o /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtend.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crtn.o /usr/local/gcc-4.7.1/m68k-uclinux/bin/ld.real: final link failed: Nonrepresentable section on output collect2: error: ld returned 1 exit status If I remove the -elf2flt option, the error goes away: $ COMPILER_PATH=/tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/:/usr/local/gcc-4.7.1/m68k-uclinux/bin/:/usr/local/gcc-4.7.1/m68k-uclinux/lib/ \ /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/collect2 --sysroot=/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data --eh-frame-hdr -o conftest -t /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crt1.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crti.o /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtbegin.o -L/tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data -L/usr/local/gcc-4.7.1/m68k-uclinux/lib/msep-data -L/tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc -L/usr/local/gcc-4.7.1/m68k-uclinux/bin -L/usr/local/gcc-4.7.1/m68k-uclinux/lib -L/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib conftest.o -lgcc -lc -lgcc /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtend.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crtn.o /usr/local/gcc-4.7.1/m68k-uclinux/bin/ld.real: mode m68kelf /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crt1.o /tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/crti.o /tmp/freescale-coldfile-xgcc/cross-gcc-4.7.1/gcc/msep-data/crtbegin.o conftest.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)__uClibc_main.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)strrchr.o (/tmp/freescale-coldfile-xgcc/freescale-coldfire-2011.09/m68k-uclinux/libc/msep-data/usr/lib/libc.a)exit.o
