[Bug c++/61282] New: vectorisation causes segfaults in a compiled program during access to an int-casted char[] after bool in a struct
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=61282 Bug ID: 61282 Summary: vectorisation causes segfaults in a compiled program during access to an int-casted char[] after bool in a struct Product: gcc Version: 4.7.2 Status: UNCONFIRMED Severity: major Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: v_pimenov at wargaming dot net Created attachment 32842 -- https://gcc.gnu.org/bugzilla/attachment.cgi?id=32842action=edit Example source file that produces segfaulting code When char[] follows a bool in a class, it is 1-byte aligned. When casted to an int later, gcc 4.7.2 can optimise some operations to use SIMD instructions that segfault on unaligned access. In this exact case body of for(i=0;ibound;i++) sum ^= p[i]; was optimised to pxor (%rdi),%xmm0 which segfaults when %rdi % sizeof(void*) != 0 To reproduce compile the attached example source file with g++ -fPIC -msse3 -O3 test.cpp run the executable and observe a SIGSEGV.

[Bug target/59904] [ARM] tls-reload-1.c fails
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59904
--- Comment #7 from wangzheyu tony.wang at arm dot com ---
After a close analysis of your elf, it will fail due to bad code in first call
to function checktls23. The corresponding C code is:
if (!y || *y++ != tls23 || *y++ != tls23_array[3]) return 0;
The code to get address of variable tls23 is wrongly fixed up. Here is the
assembly code with analysis embedded:
checktls23:
push{r4, lr}
mov r3, r0
sub r2, r0, #0
beq .L136
ldr r2, .L140 get offset of variable tls23
ldr r1, [r0]
bl __aeabi_read_tp @ load_tp_soft get thread point and save it
to r0
add r0, r0, r2thread point plus offset equals address of
variable tls23
mov r2, #0
cmp r1, r0
bne .L136
ldr r4, .L140+4
bl __aeabi_read_tp @ load_tp_soft
ldr r1, [r3, #4]
add r0, r0, r4
cmp r1, r0
bne .L136
add r3, r3, #8
mov r2, r3
.L136:
mov r0, r2
@ sp needed
pop {r4, pc}
.L141:
.align 2
.L140:
.word .LANCHOR2(tpoff)+124 offset of tls23 is correctly
generated. but never get correctly fixed up.
.word .LANCHOR3(tpoff)+12
So my advice is to use a newer version of binutils to test it again.
(In reply to christophe.lyon from comment #6)
I have re-run the tests with trunk@210140 and older binutils (Sept 2013).
The test fails at compilation with target arm-none-linux-gnueabi, and
CFLAGS=-Os -pie -fpie or -Os -pie -fPIE in the following configurations:
--with-mode=arm --with-cpu=cortex-a9
--with-mode=arm --with-cpu=cortex-a9 RUNTESTFLAGS=-mthumb
--with-mode=thumb --with-cpu=cortex-a9
--with-mode=thumb --with-cpu=cortex-a9 RUNTESTFLAGS=-marm
The test compiles OK and fails at execution with
--with-mode=thumb --with-cpu=cortex-a9 RUNTESTFLAGS=-march=armv5t
(this is the ELF file I have attached)
The compiles and runs OK with
--with-mode=arm --with-cpu=cortex-a9 RUNTESTFLAGS=-march=armv5t
