Solaris 2.7
>Description:
When gcc 3.0x compile some switch statements on Solaris
platform. It would optimize the code by search table
when multi-entry occured.
But the pseudo-opcode, .subsection and .provious cannot be
recogonized by Solaris' /usr/ccs/bin/as
The compile information is:
/usr/ccs/bin/as: "/var/tmp/ccEyovVM.s", line 438: error: unknown opcode ".subsection"
/usr/ccs/bin/as: "/var/tmp/ccEyovVM.s", line 438: error: statement syntax
/usr/ccs/bin/as: "/var/tmp/ccEyovVM.s", line 529: error: unknown opcode ".previous"
/usr/ccs/bin/as: "/var/tmp/ccEyovVM.s", line 529: error: statement syntax
>How-To-Repeat:
Compile the source code I gave with gcc 3.0x.
