Assembler command line options

ID091611 Non-Confidential

Note

This option is deprecated.

See also

• --device=name.

2.2.19 --device=name

This option selects a specified device as the target and sets the associated processor settings.

Note

This option is deprecated.

See also

• --device=list on page 2-9

• --cpu=name on page 2-8

• --device=name on page 3-68 in the Compiler Reference.

2.2.20 --diag_error=tag{, tag}

Diagnostic messages output by the assembler can be identified by a tag in the form of

{

prefix

}

number

, where the

prefix

is A. The

--diag_error

option sets the diagnostic messages

that have the specified tags to the error severity.

You can specify more than one tag with these options by separating each tag using a comma.You

can specify the optional assembler prefix

before the tag number. If any prefix other than A is

included, the message number is ignored.

Table 2-2 shows the meaning of the term severity used in the option descriptions.

You can set the

tag

warning

to treat all warnings as errors.

See also

• --brief_diagnostics on page 2-7

• --diag_warning=tag{, tag} on page 2-12

• --diag_suppress=tag{, tag} on page 2-11.

Table 2-2 Severity of diagnostic messages

Severity Description

Error Errors indicate violations in the syntactic or semantic rules of assembly

language. Assembly continues, but object code is not generated.

Warning Warnings indicate unusual conditions in your code that might indicate a

problem. Assembly continues, and object code is generated unless any

problems with an Error severity are detected.

Remark Remarks indicate common, but not recommended, use of assembly

language. These diagnostics are not issued by default. Assembly

continues, and object code is generated unless any problems with an

Error severity are detected.

2.2.21 --diag_remark=tag{, tag}

Diagnostic messages output by the assembler can be identified by a tag in the form of

{

prefix

}

number

, where the

prefix

is A. The

--diag_remark

option sets the diagnostic messages

that have the specified tags to the remark severity.

You can specify more than one tag with these options by separating each tag using a comma.You

can specify the optional assembler prefix

before the tag number. If any prefix other than A is

included, the message number is ignored.

See also

• --brief_diagnostics on page 2-7

• --diag_error=tag{, tag} on page 2-10.

2.2.22 --diag_style=style

This option instructs the assembler to display diagnostic messages using the specified

style

where

style

is one of:

arm

Display messages using the ARM assembler style. This is the default if

--diag_style

is not specified.

ide

Include the line number and character count for the line that is in error. These

values are displayed in parentheses.

gnu

Display messages using the GNU style.

Choosing the option

--diag_style=ide

implicitly selects the option

--brief_diagnostics

Explicitly selecting

--no_brief_diagnostics

on the command line overrides the selection of

--brief_diagnostics

implied by

--diag_style=ide

Selecting either the option

--diag_style=arm

or the option

--diag_style=gnu

does not imply any

selection of

--brief_diagnostics

See also

• --brief_diagnostics on page 2-7

• --diag_style=style.

2.2.23 --diag_suppress=tag{, tag}

Diagnostic messages output by the assembler can be identified by a tag in the form of

{

prefix

}

number

, where the

prefix

is A. The

--diag_suppress

option disables the diagnostic

messages that have the specified tags.

You can specify more than one tag with these options by separating each tag using a comma.

For example, to suppress the warning messages that have numbers

1293

and

187

, use the

following command:

armasm --diag_suppress=1293,187

You can specify the optional assembler prefix

before the tag number. For example:

armasm --diag_suppress=A1293,A187

If any prefix other than A is included, the message number is ignored. Diagnostic message tags

can be cut and pasted directly into a command line.

Assembler command line options

ID091611 Non-Confidential

model

can be one of:

none

Source code is not permitted to use any floating-point type or floating point

instruction. This option overrides any explicit --fpu=name option.

ieee_full

All facilities, operations, and representations guaranteed by the IEEE standard are

available in single and double-precision. Modes of operation can be selected

dynamically at runtime.

ieee_fixed

IEEE standard with round-to-nearest and no inexact exception.

ieee_no_fenv

IEEE standard with round-to-nearest and no exceptions. This mode is compatible

with the Java floating-point arithmetic model.

std

IEEE finite values with denormals flushed to zero, round-to-nearest and no

exceptions. It is C and C++ compatible. This is the default option.

Finite values are as predicted by the IEEE standard. It is not guaranteed that NaNs

and infinities are produced in all circumstances defined by the IEEE model, or

that when they are produced, they have the same sign. Also, it is not guaranteed

that the sign of zero is that predicted by the IEEE model.

fast

Some value altering optimizations, where accuracy is sacrificed to fast execution.

This is not IEEE compatible, and is not standard C.

Example

armasm --fpmode ieee_full inputfile.s

See also

• --fpu=name.

2.2.33 --fpu=list

This option lists the supported FPU names that can be used with the

--fpu=name

option.

Example

armasm --fpu=list

See also

• --fpu=name

• --fpmode=model on page 2-13.

2.2.34 --fpu=name

This option selects the target floating-point unit (FPU) architecture. If you specify this option it

overrides any implicit FPU set by the

--cpu

option. The assembler produces an error if the FPU

you specify explicitly is incompatible with the CPU. Floating-point instructions also produce

either errors or warnings if assembled for the wrong target FPU.

The assembler sets a build attribute corresponding to

name

in the object file. The linker

determines compatibility between object files, and selection of libraries, accordingly.

Valid values for

name

are:

none

Selects no floating-point architecture. This makes your assembled object

file compatible with object files built with any FPU.
