Compiler Command-line Options
rvct_c90
aeabi_clib90
aeabi_clib99
aeabi_clib
aeabi_glibc
Behaves similarly to --library_interface=rvct. The difference is
that references in the input source code to function names that are
not reserved by C90, are not modified by the compiler. Otherwise,
some C99 math.h function names might be prefixed with
__hardfp_, for example __hardfp_tgamma.
Specifies that the compiler output works with any ISO C90 library
compliant with the ARM Embedded Application Binary Interface
(AEABI).
Specifies that the compiler output works with any ISO C99 library
compliant with the ARM Embedded Application Binary Interface
(AEABI).
Specifies that the compiler output works with any ISO C library
compliant with the ARM Embedded Application Binary Interface
(AEABI).
Selecting the option --library_interface=aeabi_clib is
equivalent to specifying either --library_interface=aeabi_clib90
or --library_interface=aeabi_clib99, depending on the choice of
source language used.
The choice of source language is dependent both on the
command-line options selected and on the filename suffixes used.
Specifies that the compiler output works with an
AEABI-compliant version of the GNU C library.
Default
If you do not specify --library_interface, the compiler assumes
--library_interface=rvct.
Usage
• Use the option --library_interface=rvct to exploit the full range of compiler and
library optimizations when linking.
• Use an option of the form --library_interface=aeabi_* when linking with an
ABI-compliant C library. Options of the form --library_interface=aeabi_*
ensure that the compiler does not generate calls to any optimized functions
provided by the RVCT C library.
