gcc: Nios II Function Attributes
1
1 6.31.21 Nios II Function Attributes
1 -----------------------------------
1
1 These function attributes are supported by the Nios II back end:
1
1 'target (OPTIONS)'
1 As discussed in ⇒Common Function Attributes, this attribute
1 allows specification of target-specific compilation options.
1
1 When compiling for Nios II, the following options are allowed:
1
1 'custom-INSN=N'
1 'no-custom-INSN'
1 Each 'custom-INSN=N' attribute locally enables use of a custom
1 instruction with encoding N when generating code that uses
1 INSN. Similarly, 'no-custom-INSN' locally inhibits use of the
1 custom instruction INSN. These target attributes correspond
1 to the '-mcustom-INSN=N' and '-mno-custom-INSN' command-line
11 options, and support the same set of INSN keywords. ⇒
Nios II Options, for more information.
1
1 'custom-fpu-cfg=NAME'
1 This attribute corresponds to the '-mcustom-fpu-cfg=NAME'
1 command-line option, to select a predefined set of custom
1 instructions named NAME. ⇒Nios II Options, for more
1 information.
