21 | ; FIXME: Get rid of this one. | |
22 | mlibfuncs | |
23 | Target Report Mask(LIBFUNC) | |
24 | For intrinsics library: pass all parameters in registers | |
25 | ||
26 | mabi=mmixware | |
27 | Target Report RejectNegative InverseMask(ABI_GNU) | |
28 | Use register stack for parameters and return value | |
29 | ||
30 | mabi=gnu | |
31 | Target Report RejectNegative Mask(ABI_GNU) | |
32 | Use call-clobbered registers for parameters and return value | |
33 | ||
34 | ; FIXME: Provide a way to *load* the epsilon register. | |
35 | mepsilon | |
36 | Target Report Mask(FCMP_EPSILON) | |
37 | Use epsilon-respecting floating point compare instructions | |
38 | ||
39 | mzero-extend | |
40 | Target Report Mask(ZERO_EXTEND) | |
41 | Use zero-extending memory loads, not sign-extending ones | |
42 | ||
43 | mknuthdiv | |
44 | Target Report Mask(KNUTH_DIVISION) | |
45 | Generate divide results with reminder having the same sign as the divisor (not the dividend) | |

47 | mtoplevel-symbols | |
48 | Target Report Mask(TOPLEVEL_SYMBOLS) | |
49 | Prepend global symbols with \":\" (for use with PREFIX) | |

51 | mno-set-program-start | |
52 | Target Report RejectNegative | |
53 | Do not provide a default start-address 0x100 of the program | |
54 | ||
55 | melf | |
56 | Target Report RejectNegative | |
57 | Link to emit program in ELF format (rather than mmo) | |
58 | ||
59 | mbranch-predict | |
60 | Target Report RejectNegative Mask(BRANCH_PREDICT) | |
61 | Use P-mnemonics for branches statically predicted as taken | |
62 | ||
63 | mno-branch-predict | |
64 | Target Report RejectNegative InverseMask(BRANCH_PREDICT) | |
65 | Don't use P-mnemonics for branches | |

67 | ; We use the term "base address" since that's what Knuth uses. The base | |
68 | ; address goes in a global register. When addressing, it's more like | |
69 | ; "base address plus offset", with the offset being 0..255 from the base, | |
70 | ; which itself can be a symbol plus an offset. The effect is like having | |
71 | ; a constant pool in global registers, code offsetting from those | |
72 | ; registers (automatically causing a request for a suitable constant base | |
73 | ; address register) without having to know the specific register or the | |
74 | ; specific offset. The setback is that there's a limited number of | |
75 | ; registers, and you'll not find out until link time whether you | |
76 | ; should have compiled with -mno-base-addresses. | |
77 | mbase-addresses | |
78 | Target Report RejectNegative Mask(BASE_ADDRESSES) | |
79 | Use addresses that allocate global registers | |
80 | ||
81 | mno-base-addresses | |
82 | Target Report RejectNegative InverseMask(BASE_ADDRESSES) | |
83 | Do not use addresses that allocate global registers | |
