Commit 12a281d368e3ae115b2340c45f93b62e20759811 by rnk [gn] Remove unneeded MC dep from llvm-tblgen Tablegen does not have link time dependencies on MC. Having llvm-tblgen depend on it causes it to be rebuilt in the gn build every time somebody touches any cpp file in llvm/lib/MC* or llvm/lib/DebugInfo/Codeview*. Touching tablegen invalidates most of the rest of the build, and re-running it takes a while. This is is annoying for me when swapping between branches that touch CodeView logic. This dep was added to LLVMBuild.txt back in 2018, and presumably it was carried over into the gn build. Differential Revision: https://reviews.llvm.org/D87553

Commit ad99e34c59b80fd094a6acdbcde4869ff37dac87 by Yuanfang Chen Revert "[NewPM][CodeGen] Introduce CodeGenPassBuilder to help build codegen pipeline" This reverts commit 31ecf8d29d81d196374a562c6d2bd2c25a62861e. This reverts commit 3fdaa8602a086a3fca5f0fc8527536ac659079d0. There is laying violation for Target->CodeGen.

Commit 528554c39b098e2d9a9c7ec51c77717aa07db2a2 by qshanz [PowerPC] Set the mayRaiseFPException for FCMPUS/FCMPUD From ISA, fcmpu will raise the Floating-Point Invalid Operation Exception (SNaN) if either of the operands is a Signaling NaN by setting the bit VXSNAN. But the instruction description didn't set the mayRaiseFPException which might have impact on the scheduling or some backend optimization.

Commit 0680a3d56d8b5bcb6647a1149f0de156f72edf91 by qshanz [Power10] Enable the heuristic for Power10 and switch the sched model with P9 Model Enable the pre-ra and post-ra scheduler strategy for Power10 as we want to customize the heuristic later. And switch the scheduler model with P9 model before P10 Model is available. The NoSchedModel is modelled as in-order cpu and the pre-ra scheduler is not bi-directional which will have big impact on the scheduler.

Commit 6c8041aa0ffed827636935e59c489b1e390c8542 by sepavloff [AST][FPEnv] Keep FP options in trailing storage of CastExpr This change allow a CastExpr to have optional FPOptionsOverride object, stored in trailing storage. Of all cast nodes only ImplicitCastExpr, CStyleCastExpr, CXXFunctionalCastExpr and CXXStaticCastExpr are allowed to have FPOptions. Differential Revision: https://reviews.llvm.org/D85960
