Bug ID: 61319
Summary: The tests
c-c++-common/ubsan/float-cast-overflow-(1|2|4).c fail
on x86_64-apple-darwin*
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: dominiq at lps dot ens.fr
CC: iains at gcc dot gnu.org, mpolacek at gcc dot gnu.org
Host: x86_64-apple-darwin*
Target: x86_64-apple-darwin*
Build: x86_64-apple-darwin*
The tests c-c++-common/ubsan/float-cast-overflow-(1|2|4).c fail on
x86_64-apple-darwin* because they generate 'nan' instead of '-nan'. These
failures are silenced by the following patch

No they are supposed to generate -nan. If it does not then there is a bug
somewhere else.
Really you should report this to Apple since it is a bug in their snprintf
implementation.
Here is the code:
// FIXME: Support floating-point formatting in sanitizer_common's
// printf, and stop using snprintf here.
char Buffer[32];
snprintf(Buffer, sizeof(Buffer), "%Lg", (long double)A.Float);
Printf("%s", Buffer);

According to [1], "The sign bit does not matter". As I understand this
sentence, the "-" is optional, so the patch from Comment #0 looks correct to
me.
This test also fails on Centos 5 for the same reason.

http://stackoverflow.com/questions/8817164/signed-nan-values
If the sign bit in the underlying representation is set, this particular
implementation of printf prints -nan. There is no standard that says that it
has to, or that it shouldn't.

--- Comment #8 from christophe.lyon at st dot com ---
Using GCC trunk @210861, binutils-linaro-2.24-2014.03, I can see that
tls-reload-1.c all PASS with:
--target arm-none-linux-gnueabi --with-mode=arm --with-cpu=cortex-a9
--with-fpu=neon and target_board set to -march=armv5t.
When changing to --with-mode=thumb, I can see 10 failures at execution time,
with "-pie -fpie" and -pie -fPIE" combined with -O1, -O2, -O3
-fomit-frame-pointer, -O3 -g, and -Os.

Yeah, glibc only prints the sign since:

Can't you use -? instead of -* (or is it -\? ?) though?

Could you please provide an elf file compiled with arm-none-linux-gnueabi-gcc
-Os -g3 -pie -fpie -mthumb -march=armv5t So that we can debug under our

__LONG_LONG_MAX__ is always defined, no need to test for that.

Yes, this patch works for me on x86_64-pc-linux-gnu {,-m32} Centos 5.
BTW: IMO, the new defines should be put in float-cast.h, alongside INT128
