<h4 class="subsection">IA-64 Options</h4>
<p>These are the <code>-m</code> options defined for the Intel IA-64 architecture.
<dl>
<dt><code>-mbig-endian</code>
<dd>Generate code for a big endian target. This is the default for HP-UX.
<br><dt><code>-mlittle-endian</code>
<dd>Generate code for a little endian target. This is the default for AIX5
and Linux.
<br><dt><code>-mgnu-as</code>
<dd><dt><code>-mno-gnu-as</code>
<dd>Generate (or don't) code for the GNU assembler. This is the default.
<br><dt><code>-mgnu-ld</code>
<dd><dt><code>-mno-gnu-ld</code>
<dd>Generate (or don't) code for the GNU linker. This is the default.
<br><dt><code>-mno-pic</code>
<dd>Generate code that does not use a global pointer register. The result
is not position independent code, and violates the IA-64 ABI.
<br><dt><code>-mvolatile-asm-stop</code>
<dd><dt><code>-mno-volatile-asm-stop</code>
<dd>Generate (or don't) a stop bit immediately before and after volatile asm
statements.
<br><dt><code>-mb-step</code>
<dd>Generate code that works around Itanium B step errata.
<br><dt><code>-mregister-names</code>
<dd><dt><code>-mno-register-names</code>
<dd>Generate (or don't) <code>in</code>, <code>loc</code>, and <code>out</code> register names for
the stacked registers. This may make assembler output more readable.
<br><dt><code>-mno-sdata</code>
<dd><dt><code>-msdata</code>
<dd>Disable (or enable) optimizations that use the small data section. This may
be useful for working around optimizer bugs.
<br><dt><code>-mconstant-gp</code>
<dd>Generate code that uses a single constant global pointer value. This is
useful when compiling kernel code.
<br><dt><code>-mauto-pic</code>
<dd>Generate code that is self-relocatable. This implies <code>-mconstant-gp</code>.
This is useful when compiling firmware code.
<br><dt><code>-minline-float-divide-min-latency</code>
<dd>Generate code for inline divides of floating point values
using the minimum latency algorithm.
<br><dt><code>-minline-float-divide-max-throughput</code>
<dd>Generate code for inline divides of floating point values
using the maximum throughput algorithm.
<br><dt><code>-minline-int-divide-min-latency</code>
<dd>Generate code for inline divides of integer values
using the minimum latency algorithm.
<br><dt><code>-minline-int-divide-max-throughput</code>
<dd>Generate code for inline divides of integer values
using the maximum throughput algorithm.
<br><dt><code>-mno-dwarf2-asm</code>
<dd><dt><code>-mdwarf2-asm</code>
<dd>Don't (or do) generate assembler code for the DWARF2 line number debugging
info. This may be useful when not using the GNU assembler.
<br><dt><code>-mfixed-range=</code><var>register-range</var><code></code>
<dd>Generate code treating the given register range as fixed registers.
A fixed register is one that the register allocator can not use. This is
useful when compiling kernel code. A register range is specified as
two registers separated by a dash. Multiple register ranges can be
specified separated by a comma.
