1. _I_n_t_r_o_d_u_c_t_i_o_n
This document contains information about the
MIPSpro C compiler driver, preprocessors, and
front ends (both traditional and ANSI C). The
MIPSpro C compiler supports compilation in three
modes: 32-bit (-32), 64-bit (-64) and High
Performance 32-bit (-n32). The default
compilation mode on all non-R8000 systems is
-_3_2, while the default on all R8000 systems is
-_6_4.
Compilation in 32-bit mode is fully compatible
with the Irix 5.3 compilers with two important
exceptions:
+o Starting with this release, default 32-bit
compilations will produce mips2 objects
instead of the mips1 objects generated in
previous releases.
+o Common object file format (COFF) is no
longer supported.
Compilation in 64-bit mode follows the LP64 data
type model, where _l_o_n_g _i_n_t and _p_o_i_n_t_e_r types are
64 bits wide. For more information about 64-bit
compilations, please consult the _M_I_P_S_p_r_o _6_4-_b_i_t
_P_o_r_t_i_n_g _a_n_d _T_r_a_n_s_i_t_i_o_n _G_u_i_d_e.
Compilation in the n32 mode incorporates data
type sizes from the 32-bit mode with calling
conventions and code generation from the 64-bit
mode. For more information about n32, please
consult the _M_I_P_S_p_r_o _N_3_2 _A_B_I _H_a_n_d_b_o_o_k.
Utilities, header files, and libraries common to
several languages are covered in the 6.2 _B_a_s_e
_D_e_v_e_l_o_p_m_e_n_t _R_e_l_e_a_s_e _N_o_t_e_s (accessed as the
ccccoooommmmppppiiiilllleeeerrrr____ddddeeeevvvv release notes).

After you install the online documentation for a
product (the _r_e_l_n_o_t_e_s subsystem), you can view
the release notes on your screen.
If you have a graphics system, select ``Release
Notes'' from the Tools submenu of the Toolchest.
This displays the _g_r_e_l_n_o_t_e_s(1) graphical browser
for the online release notes. Refer to the
_g_r_e_l_n_o_t_e_s(1) man page for information on options
to this command.
If you do not have a graphics system, you can
use the _r_e_l_n_o_t_e_s command. Refer to the
_r_e_l_n_o_t_e_s(1) man page for accessing the online
release notes.
