Hello,
When I try to compile a program using the 'regex' module on Solaris 10,
I get the output
/opt/solarisstudio12.3/bin/c99 -Xc -D_XPG6 -DHAVE_CONFIG_H -I. -I../..
-D_REENTRANT -I/opt/csw/include -c -o regex.o regex.c
"regex_internal.h", line 105: warning: macro redefined: gettext
"regex_internal.h", line 734: warning: token-less macro argument
Assembler: "/tmp/yabeAAAiUaidC", line 19010 : Value out of range
"/tmp/yabeAAAiUaidC", line 19031 : Value out of range
Failure in /opt/solarisstudio12.3/prod/bin/fbe, status = 0x7f00
Fatal Error exec'ing /opt/solarisstudio12.3/prod/bin/fbe
c99: acomp failed for regex.c
The warnings about macros are harmless, but the "Value out of range"
errors are fatal.
I re-ran with the -S option to get assembler output:
/opt/solarisstudio12.3/bin/c99 -Xc -D_XPG6 -DHAVE_CONFIG_H -I. -I../..
-D_REENTRANT -I/opt/csw/include -c -o regex.o regex.c -S
Then if I try to compile the regex.o file:
mv regex.o regex.S
/opt/solarisstudio12.3/bin/c99 -Xc -D_XPG6 -DHAVE_CONFIG_H -I. -I../..
-D_REENTRANT -I/opt/csw/include -c -o regex.o regex.S
Assembler: "regex.S", line 21273 : Value out of range
"regex.S", line 21294 : Value out of range
c99: fbe failed for regex.S
Line 21273 is
subl $4294967296,%eax
Line 21294 is
subl $4294967296,%eax
I think the error is that these constants are too large. 4,294,967,296
is 2 ** 32 which is too big a value to fit in 32 bits.
When I try again with the Gnulib from 2016-12-15, this file compiles OK,
but when I apply the patch from
http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg00666.html
the problem occurs. I believe that the faulty code is coming from the
use of INT_ADD_WRAPV from intprops.h. I haven't investigated how exactly
this macro leads to the faulty code. Hopefully I am on the right track
here and someone will have an idea of how to fix it. If not, I will have
to study what this macro does and why it is being used here.
Thanks,
Gavin
