The routines are defined statically. You can set breakpoints 30 on them in gdb by naming the including source file; e.g., 31 'coff-mips.c':ecoff_swap_hdr_in. 32 33 Before including this header file, one of ECOFF_32, ECOFF_64, 34 ECOFF_SIGNED_32 or ECOFF_SIGNED_64 must be defined. These are 35 checked when swapping information that depends upon the target 36 size. This code works for 32 bit and 64 bit ECOFF, but may need to 37 be generalized in the future. 38 39 Some header file which defines the external forms of these 40 structures must also be included before including this header file. 41 Currently this is either coff/mips.h or coff/alpha.h. 42 43 If the symbol TEST is defined when this file is compiled, a 44 comparison is made to ensure that, in fact, the output is 45 bit-for-bit the same as the input. Of course, this symbol should 46 only be defined when deliberately testing the code on a machine 47 with the proper byte sex and such. */ 48 49 #ifdef ECOFF_32 50 #define ECOFF_GET_OFF H_GET_32 51 #define ECOFF_PUT_OFF H_PUT_32 52 #endif 53 #ifdef ECOFF_64 54 #define ECOFF_GET_OFF H_GET_64 55 #define ECOFF_PUT_OFF H_PUT_64 56 #endif 57 #ifdef ECOFF_SIGNED_32 58 #define ECOFF_GET_OFF H_GET_S32 59 #define ECOFF_PUT_OFF H_PUT_S32 60 #endif 61 #ifdef ECOFF_SIGNED_64 62 #define ECOFF_GET_OFF H_GET_S64 63 #define ECOFF_PUT_OFF H_PUT_S64 64 #endif 65 66 /* ECOFF auxiliary information swapping routines.
