- These routines are to get and set the floating-point control registers of
- MIPS floating-point units. All of these routines take and or return
- their values as 32 bit integers.
-
- The file <_s_y_s/_f_p_u._h> contains unions for each of the control registers.
- Each union contains a structure that breaks out the bit fields into the
- logical parts for each control register. This file also contains
- constants for fields of the control registers.
-
- All implementations of MIPS floating-point have a _c_o_n_t_r_o_l _a_n_d _s_t_a_t_u_s
- register and a _i_m_p_l_e_m_e_n_t_a_t_i_o_n _r_e_v_i_s_i_o_n register. The _c_o_n_t_r_o_l _a_n_d _s_t_a_t_u_s
- register is returned by _g_e_t__f_p_c__c_s_r. The routine _s_e_t__f_p_c__c_s_r sets the
- _c_o_n_t_r_o_l _a_n_d _s_t_a_t_u_s register and returns the old value. The
- _i_m_p_l_e_m_e_n_t_a_t_i_o_n _r_e_v_i_s_i_o_n register is read-only and is returned by the
- routine _g_e_t__f_p_c__i_r_r.
-
- The routine _s_w_a_p_R_M sets only the rounding mode and returns the old
- rounding mode. The routine _s_w_a_p_I_N_X sets only the sticky inexact bit and
- returns the old one. The bits in the arguments and return values to
- _s_w_a_p_R_M and _s_w_a_p_I_N_X are right justified.

- _s_w_a_p_R_M and _s_w_a_p_I_N_X are in _l_i_b_m._a . The link editor searches this library
- under the "-lm" option.
