3.19.37 PDP-11 Options

These options are defined for the PDP-11:

+-mfpu +
+

Use hardware FPP floating point. This is the default. (FIS floating point on the PDP-11/40 is not supported.) Implies -m45.

+-msoft-float +
+

Do not use hardware floating point.

+-mac0 +
+

Return floating-point results in ac0 (fr0 in Unix assembler syntax).

+-mno-ac0 +
+

Return floating-point results in memory. This is the default.

+-m40 +
+

Generate code for a PDP-11/40. Implies -msoft-float -mno-split.

+-m45 +
+

Generate code for a PDP-11/45. This is the default.

+-m10 +
+

Generate code for a PDP-11/10. Implies -msoft-float -mno-split.

+ -mint16 +
-mno-int32
+

Use 16-bit int. This is the default.

+ -mint32 +
-mno-int16
+

Use 32-bit int.

+-msplit +
+

Target has split instruction and data space. Implies -m45.

+-munix-asm +
+

Use Unix assembler syntax.

+-mdec-asm +
+

Use DEC assembler syntax.

+-mgnu-asm +
+

Use GNU assembler syntax. This is the default.

+-mlra +
