From 61ffdd1d822cded8cecc95731a8bc06a6cc225b6 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Tue, 18 Sep 2001 09:57:26 +0000 Subject: 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. --- bfd/nlm32-ppc.c | 54 ++++++++++++++++++++++++++++-------------------------- 1 file changed, 28 insertions(+), 26 deletions(-) (limited to 'bfd/nlm32-ppc.c') diff --git a/bfd/nlm32-ppc.c b/bfd/nlm32-ppc.c index 0401d1efc7..98410a8d50 100644 --- a/bfd/nlm32-ppc.c +++ b/bfd/nlm32-ppc.c @@ -1,5 +1,5 @@ /* Support for 32-bit PowerPC NLM (NetWare Loadable Module) - Copyright 1994, 1995, 2000 Free Software Foundation, Inc. + Copyright 1994, 1995, 2000, 2001 Free Software Foundation, Inc.
