The routines are defined statically. You can set breakpoints 29 on them in gdb by naming the including source file; e.g., 30 'coff-mips.c':ecoff_swap_hdr_in. 31 32 Before including this header file, one of ECOFF_32, ECOFF_64, 33 ECOFF_SIGNED_32 or ECOFF_SIGNED_64 must be defined. These are 34 checked when swapping information that depends upon the target 35 size. This code works for 32 bit and 64 bit ECOFF, but may need to 36 be generalized in the future. 37 38 Some header file which defines the external forms of these 39 structures must also be included before including this header file. 40 Currently this is either coff/mips.h or coff/alpha.h. 41 42 If the symbol TEST is defined when this file is compiled, a 43 comparison is made to ensure that, in fact, the output is 44 bit-for-bit the same as the input. Of course, this symbol should 45 only be defined when deliberately testing the code on a machine 46 with the proper byte sex and such. */ 47 48 #ifdef ECOFF_32 49 #define ECOFF_GET_OFF H_GET_32 50 #define ECOFF_PUT_OFF H_PUT_32 51 #endif 52 #ifdef ECOFF_64 53 #define ECOFF_GET_OFF H_GET_64 54 #define ECOFF_PUT_OFF H_PUT_64 55 #endif 56 #ifdef ECOFF_SIGNED_32 57 #define ECOFF_GET_OFF H_GET_S32 58 #define ECOFF_PUT_OFF H_PUT_S32 59 #endif 60 #ifdef ECOFF_SIGNED_64 61 #define ECOFF_GET_OFF H_GET_S64 62 #define ECOFF_PUT_OFF H_PUT_S64 63 #endif 64 65 /* ECOFF auxiliary information swapping routines.
