[CostModel] getCFInstrCost in getUserCost. Have BasicTTI call the base implementation so that both agree on the default behaviour, which the default being a cost of '1'. This has required an X86 specific implementation as it seems to be very reliant on those instructions being free. Changes are also made to AMDGPU so that their implementations distinguish between cost kinds, so that the unrolling isn't affected. PowerPC also has its own implementation to prevent changes to the reg-usage vectorizer test. The cost model test changes now reflect that ret instructions are not generally free.

[CostModel] mostly remove cost-kind predicate for intrinsics in basic TTI implementation This is re-applying a combination of f7eac51b9b3f and 8ec7ea3ddce7 as one patch to avoid regressions now that we have better testing in place. Those were reverted with 32dd5870ee31 because of crashing in experimental intrinsics. That bug should be fixed with 7ae346434. Paraphrased original commit messages: This is the last step in removing cost-kind as a consideration in the basic class model for intrinsics. See D89461 for the start of that. Subsequent commits dealt with each of the special-case intrinsics that had customization here in the basic class. This should remove a barrier to retrying D87188 (canonicalization to the abs intrinsic). The ARM and x86 cost diffs seen here may be wrong because the target-specific overrides have their own bugs, but we hope this is less wrong - if something has a significant throughput cost, then it should have a significant size / blended cost too by default. The only behavioral diff in current regression tests is shown in the x86 scatter-gather test (which is misplaced or broken because it runs the entire -O3 pipeline) - we unrolled less, and we assume that is a improvement. Exception: in general, we want the *size* cost for a scalar call to be cheap even if the other costs are expensive - we expect it to just be a branch with some optional stack manipulation. It is likely that we will want to carve out some exceptions/overrides to this rule as follow-up patches for calls that have some general and/or target-specific difference to the expected lowering.

[CostModel] mostly remove cost-kind predicate for intrinsics in basic TTI implementation This is re-applying a combination of f7eac51b9b3f and 8ec7ea3ddce7 as one patch to avoid regressions now that we have better testing in place. Those were reverted with 32dd5870ee31 because of crashing in experimental intrinsics. That bug should be fixed with 7ae346434. Paraphrased original commit messages: This is the last step in removing cost-kind as a consideration in the basic class model for intrinsics. See D89461 for the start of that. Subsequent commits dealt with each of the special-case intrinsics that had customization here in the basic class. This should remove a barrier to retrying D87188 (canonicalization to the abs intrinsic). The ARM and x86 cost diffs seen here may be wrong because the target-specific overrides have their own bugs, but we hope this is less wrong - if something has a significant throughput cost, then it should have a significant size / blended cost too by default. The only behavioral diff in current regression tests is shown in the x86 scatter-gather test (which is misplaced or broken because it runs the entire -O3 pipeline) - we unrolled less, and we assume that is a improvement. Exception: in general, we want the *size* cost for a scalar call to be cheap even if the other costs are expensive - we expect it to just be a branch with some optional stack manipulation. It is likely that we will want to carve out some exceptions/overrides to this rule as follow-up patches for calls that have some general and/or target-specific difference to the expected lowering.

The only behavioral diff in current regression tests is shown in the x86 scatter-gather test (which is misplaced or broken because it runs the entire -O3 pipeline) - we unrolled less, and we assume that is a improvement. Exception: in general, we want the *size* cost for a scalar call to be cheap even if the other costs are expensive - we expect it to just be a branch with some optional stack manipulation. It is likely that we will want to carve out some exceptions/overrides to this rule as follow-up patches for calls that have some general and/or target-specific difference to the expected lowering. This was noticed as a regression in unrolling, so we have a test for that now along with a couple of direct cost model tests. If the assumed scalarization costs for the oversized vector calls are not realistic, that would be another follow-up refinement of the cost models.

[CostModel] mostly remove cost-kind predicate for intrinsics in basic TTI implementation This is re-applying a combination of f7eac51b9b3f and 8ec7ea3ddce7 as one patch to avoid regressions now that we have better testing in place.

[CostModel] getCFInstrCost in getUserCost. Have BasicTTI call the base implementation so that both agree on the default behaviour, which the default being a cost of '1'. This has required an X86 specific implementation as it seems to be very reliant on those instructions being free. Changes are also made to AMDGPU so that their implementations distinguish between cost kinds, so that the unrolling isn't affected. PowerPC also has its own implementation to prevent changes to the reg-usage vectorizer test. The cost model test changes now reflect that ret instructions are not generally free.

[CostModel] mostly remove cost-kind predicate for intrinsics in basic TTI implementation This is re-applying a combination of f7eac51b9b3f and 8ec7ea3ddce7 as one patch to avoid regressions now that we have better testing in place. Those were reverted with 32dd5870ee31 because of crashing in experimental intrinsics. That bug should be fixed with 7ae346434. Paraphrased original commit messages: This is the last step in removing cost-kind as a consideration in the basic class model for intrinsics. See D89461 for the start of that. Subsequent commits dealt with each of the special-case intrinsics that had customization here in the basic class. This should remove a barrier to retrying D87188 (canonicalization to the abs intrinsic). The ARM and x86 cost diffs seen here may be wrong because the target-specific overrides have their own bugs, but we hope this is less wrong - if something has a significant throughput cost, then it should have a significant size / blended cost too by default. The only behavioral diff in current regression tests is shown in the x86 scatter-gather test (which is misplaced or broken because it runs the entire -O3 pipeline) - we unrolled less, and we assume that is a improvement. Exception: in general, we want the *size* cost for a scalar call to be cheap even if the other costs are expensive - we expect it to just be a branch with some optional stack manipulation. It is likely that we will want to carve out some exceptions/overrides to this rule as follow-up patches for calls that have some general and/or target-specific difference to the expected lowering. This was noticed as a regression in unrolling, so we have a test for that now along with a couple of direct cost model tests. If the assumed scalarization costs for the oversized vector calls are not realistic, that would be another follow-up refinement of the cost models.

[CostModel] mostly remove cost-kind predicate for intrinsics in basic TTI implementation This is re-applying a combination of f7eac51b9b3f and 8ec7ea3ddce7 as one patch to avoid regressions now that we have better testing in place. Those were reverted with 32dd5870ee31 because of crashing in experimental intrinsics. That bug should be fixed with 7ae346434. Paraphrased original commit messages: This is the last step in removing cost-kind as a consideration in the basic class model for intrinsics. See D89461 for the start of that. Subsequent commits dealt with each of the special-case intrinsics that had customization here in the basic class. This should remove a barrier to retrying D87188 (canonicalization to the abs intrinsic). The ARM and x86 cost diffs seen here may be wrong because the target-specific overrides have their own bugs, but we hope this is less wrong - if something has a significant throughput cost, then it should have a significant size / blended cost too by default. The only behavioral diff in current regression tests is shown in the x86 scatter-gather test (which is misplaced or broken because it runs the entire -O3 pipeline) - we unrolled less, and we assume that is a improvement. Exception: in general, we want the *size* cost for a scalar call to be cheap even if the other costs are expensive - we expect it to just be a branch with some optional stack manipulation. It is likely that we will want to carve out some exceptions/overrides to this rule as follow-up patches for calls that have some general and/or target-specific difference to the expected lowering. This was noticed as a regression in unrolling, so we have a test for that now along with a couple of direct cost model tests. If the assumed scalarization costs for the oversized vector calls are not realistic, that would be another follow-up refinement of the cost models.
