43 * named ctors sections, but that hasn't been done either. So if we don't

558 -Xpg4plus -a xpg4plus
559 -Xods30 -a ods30
560
561 As with SCO, the default is XPG4 plus mode. SCO also allows you to
562 specify a C dialect with -Xt, -Xa, -Xc, -Xk and -Xm. These are passed
563 on to the assembler and linker in the same way that the SCO compiler
564 does.
565
566 SCO also allows you to compile, link and generate either ELF or COFF

125 Parameters which can be passed to gcc, and their SCO equivalents:
126 GCC Parameter SCO Equivalent
127 -ansi -a ansi
128 -posix -a posix

133 As with SCO, the default is XPG4 plus mode. SCO also allows you to
134 specify a C dialect with -Xt, -Xa, -Xc, -Xk and -Xm. These are passed
135 on to the assembler and linker in the same way that the SCO compiler
136 does.
137
138 SCO also allows you to compile, link and generate either ELF or COFF
567 binaries. With gcc, unlike the SCO compiler, the default is ELF.
568 Specify -mcoff to gcc to produce COFF binaries. -fpic will get the
569 assembler and linker to produce PIC code.
139 binaries. With gcc, we now only support ELF mode.
140
141 GCC also requires that the user has installed OSS646, the Execution
142 Environment Update, or is running release 5.0.7 or later. This has
143 many fixes to the ELF link editor and assembler, and a considerably
144 improved libc and RTLD.
145
146 In terms of tool usage, we want to use the standard link editor always,
147 and either the GNU assembler or the native assembler. With OSS646 the
148 native assembler has grown up quite a bit. Some of the specs below
149 assume that /usr/gnu is the prefix for the GNU tools, because thats
150 where the SCO provided ones go. This is especially important for
151 include and library search path ordering. We want to look in /usr/gnu
152 first, becuase frequently people are linking against -lintl, and they
153 MEAN to link with gettext. What they get is the SCO intl library. Its
154 a REAL pity that GNU gettext chose that name; perhaps in a future
155 version they can be persuaded to change it to -lgnuintl and have a
156 link so that -lintl will work for other systems. The same goes for
157 header files. We want /usr/gnu/include searched for before the system
158 header files. Hence the -isystem /usr/gnu/include in the CPP_SPEC.
159 We get /usr/gnu/lib first by virtue of the MD_STARTFILE_PREFIX below.

724Here comes some major hackery to get the crt stuff to compile properly.
725Since we can (and do) compile for both COFF and ELF environments, we
726set things up accordingly, based on the pre-processor defines for ELF
727and COFF. This is insane, but then I guess having one compiler with a
728single back-end supporting two vastly different file format types is
729a little insane too. But it is not impossible and we get a useful
730compiler at the end of the day. Onward we go ...
