Alan Modra	dc810e3900	Touches most files in bfd/, so likely will be blamed for everything.. o bfd_read and bfd_write lose an unnecessary param and become bfd_bread and bfd_bwrite. o bfd_alloc now all take a bfd_size_type arg, and will error if size_t is too small. eg. 32 bit host, 64 bit bfd, verrry big files or bugs in linker scripts etc. o file_ptr becomes a bfd_signed_vma. Besides matching sizes with various other types involved in handling sections, this should make it easier for bfd to support a 64 bit off_t on 32 bit hosts that provide it. o I've made the H_GET_ and H_PUT_* macros (which invoke bfd_h_{get,put}_) generally available. They now cast their args to bfd_vma and bfd_byte as appropriate, which removes a swag of casts from the source. o Bug fixes to bfd_get8, aix386_core_vec, elf32_h8_relax_section, and aout-encap.c. o Zillions of formatting and -Wconversion fixes.	25 years ago

Stan Shebs	071ea11e85	Initial creation of sourceware repository	28 years ago
Ken Raeburn	ede4eed483	Added new files elflink.c, elflink.h, elfcore.h. Moved some mostly size-independent stuff from elfcode.h to elf.c, adding a data structure to elfcode.h with some misc data and callback functions. Added a pointer to that structure to the target back end data. More work can be done here. Renamed generic elf routines (not cpu-specific stuff) to start with bfd_elf or _bfd_elf. Updated most call sites, sometimes defined some macros. Moved some dynamic linking support code from m68k, sparc, i386 to common files, using target back end flags to control behavior. More work can probably be done here too. Moved core- and linker-support code out of elfcode.h to elf.c, elfcore.h, elflink.h, or elflink.c. Now elfcode.h contains only .o and executable support, plus #includes of elfcore.h and elflink.h. Much of the contents of these other header files can probably still be moved from the .h files to the .c files, to get compiled only once. Cleaned up some "gcc -Wall" warnings regarding unused or uninitialized variables, in generic and cpu-specific code.	32 years ago
