On Solaris 11 2011-11 the vendor gcc 4.5.2 cannot compile gnulib's mktime.c:
$ make
...
gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -DGNULIB_STRICT_CHECKING=1 -Wall
-D_REENTRANT -g -O2 -MT mktime.o -MD -MP -MF $depbase.Tpo -c -o mktime.o
mktime.c &&\
mv -f $depbase.Tpo $depbase.Po
Assembler: mktime.c
"/var/tmp//ccGla4PN.s", line 10 : .align test amount has negative value
"/var/tmp//ccGla4PN.s", line 131 : .align test amount has negative value
"/var/tmp//ccGla4PN.s", line 355 : .align test amount has negative value
"/var/tmp//ccGla4PN.s", line 1111 : .align test amount has negative
value
*** Error code 1
Indeed, find attached the output of
$ gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -DGNULIB_STRICT_CHECKING=1 -Wall
-D_REENTRANT -O2 -S mktime.c -o mktime1.s
$ gcc -std=gnu99 -DHAVE_CONFIG_H -I. -I.. -DGNULIB_STRICT_CHECKING=1 -Wall
-D_REENTRANT -O2 -S mktime.c -DWRAPV -o mktime2.s
As you can see, the use of
#pragma GCC optimize ("wrapv")
apparently replaces the valid asm statements
.p2align 4,,15
with
.p2align 4,,-1
For the semantics of .p2align, see
http://sourceware.org/binutils/docs/as/P2align.html
I can reproduce the effect with gcc-4.5.2 built from source on a glibc system.
The difference is that the GNU assembler accepts the .p2align 4,,-1
pseudo-instruction, while the Solaris assembler doesn't.
I've registered this bug as <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51793>.
As a workaround, I would propose to emit this #pragma only on platforms
where we can be sure that GNU as is used. Namely, glibc systems.
