style warnings that have annoyed my once too often.
things like the .note.netbsd.ident section are provided by crti/crtn.
crti/crtn also provide the _init() and _fini() routines.
crtbegin/crtend now only provide support for ctors/dtors. This paves
the way to using the "crtstuff" provided with GCC (when we upgrade to
GCC 3.3), which provides, among other things, much better C++/Java
exception handling.
macho_hdr, argc, *argv, NULL, *envp, NULL, progname, NULL,
*progname, **argv, **envp
Where progname is a pointer to the program name as given in the first
argument to execve(), and macho_hdr a pointer to the Mach-O header at
the beginning of the executable file.
* If -mhard-float is passed to the compiler, pass -mfpa10 to the assembler.
* If -msoft-float is passed to the compiler, pass -mfpu=softvfp to the
assembler.
* If neither -mhard-float nor -msoft-float are passed to the compiler,
pass -mfpu=softvfp to the assembler.
These changes properly mark objects as using soft-VFP, as is the default
code generation for NetBSD ARM ELF.
* FPU_MEMMULTI -- only include the FPU_FPA10 bit.
* FPU_ARCH_VFP -- define, meaning "uses VFP-format layout".
* FPU_FPA -- define short-hand for (FPU_CORE|FPU_FPA10).
* FPU_DEFAULT -- FPU_ALL -> FPU_FPA.
* Floating point instructions -- FPU_ALL -> FPU_FPA.
* Also set F_SOFT_FLOAT if FPU_ARCH_VFP.
* Set F_VFP_FLOAT if FPU_ARCH_VFP.
* md_atof: lay out bytes properly if using VFP.
* Accept -mfpu=softvfp.
* For -mall, set the FPU part of cpu_variant to FPU_FPA, instead of
FPU_ALL.
pdc202xx_setup_channel, pdc20268_setup_channel:
Properly compute the address of the DMA control register for channel 1.
I think the controllers ignore these bits, I suspect it's only there so that
the BIOS can tell the OS is has configured DMA, but better be correct.
Thanks to Alexander Yurchenko for pointing this out.
- c_gets() was usually returning a length, but sometimes
one of the CC_xxx values (which are small +ve integers)!
- fixed c_gets() by putting a ' ' under the cursor.
