`-xcode=`a

SPARC: Specifies the code address space.

Values

a must be one of the following:

Value of a	Meaning
`abs32`	Generates 32-bit absolute addresses, which are fast, but have limited range. Code + data + bss size is limited to 2**32 bytes.
`abs44`	SPARC: Generates 44-bit absolute addresses, which have moderate speed and moderate range. Code + data + bss size is limited to 2**44 bytes. Available only on 64-bit architectures: `-xarch=(v9\|v9a)`
`abs64`	SPARC: Generates 64-bit absolute addresses, which are slow, but have full range. Available only on 64-bit architectures: `-xarch=(v9\|v9a)`
`pic13`	Generates position-independent code (small model), which is fast, but has limited range. Equivalent to `-Kpic`. Permits references to at most 211 unique external symbols on 32-bit architectures; 210 on 64-bit.
`pic32`	Generates position-independent code (large model), which is slow, but has full range. Equivalent to `-KPIC`. Permits references to at most 230 unique external symbols on 32-bit architectures; 229 on 64-bit.

Value of a

Meaning

abs32

Generates 32-bit absolute addresses, which are fast, but have limited range. Code + data + bss size is limited to 2**32 bytes.

abs44

SPARC: Generates 44-bit absolute addresses, which have moderate speed and moderate range. Code + data + bss size is limited to 2**44 bytes. Available only on 64-bit architectures:

-xarch=(v9|v9a)

abs64

SPARC: Generates 64-bit absolute addresses, which are slow, but have full range. Available only on 64-bit architectures:

-xarch=(v9|v9a)

pic13

Generates position-independent code (small model), which is fast, but has limited range. Equivalent to -Kpic. Permits references to at most 2**11 unique external symbols on 32-bit architectures; 2**10 on 64-bit.

pic32

Generates position-independent code (large model), which is slow, but has full range. Equivalent to -KPIC. Permits references to at most 2**30 unique external symbols on 32-bit architectures; 2**29 on 64-bit.

Defaults

For SPARC V8 and V7 processors, the default is -xcode=abs32.

For SPARC and UltraSPARC processors (with -xarch=(v9|v9a)), the default is -xcode=abs64.

Interactions

When building shared dynamic libraries with -xarch=v9 or -xarch=v9a using 64-bit Solaris 7 software, the -xcode=pic13 or -xcode=pic32 (or -pic or -PIC) option must be specified.
