[mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.

Make it possible for ints/floats to return different values from getBooleanContents() Summary: On MIPS32r6/MIPS64r6, floating point comparisons return 0 or -1 but integer comparisons return 0 or 1. Updated the various uses of getBooleanContents. Two simplifications had to be disabled when float and int boolean contents differ: - ScalarizeVecRes_VSELECT except when the kind of boolean contents is trivially discoverable (i.e. when the condition of the VSELECT is a SETCC node). - visitVSELECT (select C, 0, 1) -> (xor C, 1). Come to think of it, this one could test for the common case of 'C' being a SETCC too. Preserved existing behaviour for all other targets and updated the affected MIPS32r6/MIPS64r6 tests. This also fixes the pi benchmark where the 'low' variable was counting in the wrong direction because it thought it could simply add the result of the comparison.

[mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.

Make it possible for ints/floats to return different values from getBooleanContents() Summary: On MIPS32r6/MIPS64r6, floating point comparisons return 0 or -1 but integer comparisons return 0 or 1. Updated the various uses of getBooleanContents. Two simplifications had to be disabled when float and int boolean contents differ: - ScalarizeVecRes_VSELECT except when the kind of boolean contents is trivially discoverable (i.e. when the condition of the VSELECT is a SETCC node). - visitVSELECT (select C, 0, 1) -> (xor C, 1). Come to think of it, this one could test for the common case of 'C' being a SETCC too. Preserved existing behaviour for all other targets and updated the affected MIPS32r6/MIPS64r6 tests. This also fixes the pi benchmark where the 'low' variable was counting in the wrong direction because it thought it could simply add the result of the comparison.

[mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.

Make it possible for ints/floats to return different values from getBooleanContents() Summary: On MIPS32r6/MIPS64r6, floating point comparisons return 0 or -1 but integer comparisons return 0 or 1. Updated the various uses of getBooleanContents. Two simplifications had to be disabled when float and int boolean contents differ: - ScalarizeVecRes_VSELECT except when the kind of boolean contents is trivially discoverable (i.e. when the condition of the VSELECT is a SETCC node). - visitVSELECT (select C, 0, 1) -> (xor C, 1). Come to think of it, this one could test for the common case of 'C' being a SETCC too. Preserved existing behaviour for all other targets and updated the affected MIPS32r6/MIPS64r6 tests. This also fixes the pi benchmark where the 'low' variable was counting in the wrong direction because it thought it could simply add the result of the comparison.

Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits.

[mips][mips64r6] c.cond.fmt, mov[fntz], and mov[fntz].[ds] are not available on MIPS32r6/MIPS64r6 Summary: c.cond.fmt has been replaced by cmp.cond.fmt. Where c.cond.fmt wrote to dedicated condition registers, cmp.cond.fmt writes 1 or 0 to normal FGR's (like the GPR comparisons). mov[fntz] have been replaced by seleqz and selnez. These instructions conditionally zero a register based on a bool in a GPR. The results can then be or'd together to act as a select without, for example, requiring a third register read port. mov[fntz].[ds] have been replaced with sel.[ds] MIPS64r6 currently generates unnecessary sign-extensions for most selects. This is because the result of a SETCC is currently an i32. Bits 32-63 are undefined in i32 and the behaviour of seleqz/selnez would otherwise depend on undefined bits. Later, we will fix this by making the result of SETCC an i64 on MIPS64 targets.

Make it possible for ints/floats to return different values from getBooleanContents() Summary: On MIPS32r6/MIPS64r6, floating point comparisons return 0 or -1 but integer comparisons return 0 or 1. Updated the various uses of getBooleanContents. Two simplifications had to be disabled when float and int boolean contents differ: - ScalarizeVecRes_VSELECT except when the kind of boolean contents is trivially discoverable (i.e. when the condition of the VSELECT is a SETCC node). - visitVSELECT (select C, 0, 1) -> (xor C, 1). Come to think of it, this one could test for the common case of 'C' being a SETCC too. Preserved existing behaviour for all other targets and updated the affected MIPS32r6/MIPS64r6 tests. This also fixes the pi benchmark where the 'low' variable was counting in the wrong direction because it thought it could simply add the result of the comparison.

Make it possible for ints/floats to return different values from getBooleanContents() Summary: On MIPS32r6/MIPS64r6, floating point comparisons return 0 or -1 but integer comparisons return 0 or 1. Updated the various uses of getBooleanContents. Two simplifications had to be disabled when float and int boolean contents differ: - ScalarizeVecRes_VSELECT except when the kind of boolean contents is trivially discoverable (i.e. when the condition of the VSELECT is a SETCC node). - visitVSELECT (select C, 0, 1) -> (xor C, 1). Come to think of it, this one could test for the common case of 'C' being a SETCC too. Preserved existing behaviour for all other targets and updated the affected MIPS32r6/MIPS64r6 tests. This also fixes the pi benchmark where the 'low' variable was counting in the wrong direction because it thought it could simply add the result of the comparison.
