C and C++ Compilers

to place a function at a particular address in memory. If you are using

third-party code, you do not have to change the source, but you must

recompile (unless the code was already compiled with the -zo option).

pragma arm section

This pragma specifies the code or data section name used for subsequent

functions or objects. This includes definitions of anonymous objects the

compiler creates for initializations.

Use a scatter-loading description file with the linker to control placing a

named section at a particular address in memory (see Pragmas

controlling code generation on page 3-4 and the ADS Linker and Utilities

Guide).

Setting byte order

-littleend

This option generates code for an ARM processor using little-endian

memory. With little-endian memory, the least significant byte of a word

has lowest address. This is the default.

-bigend

This option generates code for an ARM processor using big-endian

memory. With big-endian memory, the most significant byte of a word

has lowest address.

Setting alignment options

-zasNumber

This option specifies the minimum byte alignment for structures. Valid

values for

Number

are:

1, 2, 4, 8

The default is 1. This option is deprecated and will not be supported in

future versions of the product.

-memaccess option

This option indicates to the compiler that the memory in the target system

has slightly restricted or expanded capabilities. By default, ARM

compilers assume that the memory system can load and store words at

4-byte alignment, halfwords at 2-byte alignment, and bytes. Load and

store capability can be indicated by specifying

option

+L41

The memory can return the aligned word containing the

addressed byte. This is useful only with ARM architecture v3

processors that lack load halfword.
