This appendix describes the technical changes between released issues of this book.
|Where appropriate, changed the terminology that implied that 16-bit Thumb and 32-bit Thumb are separate instruction sets.||Various topics.|
Where appropriate, rather than 16-bit Thumb or 32-bit Thumb, referred instead to Thumb or Thumb-2 technology.
|Explicitly stated that there are two ways to tailor I/O functions, with guidance about use.||Tailoring input/output functions in the C and C++ libraries|
|Made the terms for system I/O functions more consistent, and gave an example of how to redefine the functions.|
|Clarified the type of division by zero in the
example. Removed the incorrect floating point error values for ||ISO-compliant implementation of signals supported by the signal() function in the C library and additional type arguments|
|Changed the ARMCC||ARM C and C++ library directory structure|
|Added the values for the arguments to the SIGFPE signal.||ISO-compliant implementation of signals supported by the signal() function in the C library and additional type arguments|
|Removed ||ISO C features missing from microlib|
|Corrected the library naming conventions.||C and C++ library naming conventions|
|Added ||Differences between microlib and the default C library|
Added a table footnote for signals SIGILL, SIGINT, SIGSEGV, and SIGTERM.
Changed the description for SIGCPPL.
Also updated the Caution.
