2018-05-09Make std::function tolerate semantically non-CopyConstructible objectsJonathan Wakely3-7/+57
To satisfy the CopyConstructible requirement a callable object stored in a std::function must behave the same when copied from a const or non-const source. If copying a non-const object doesn't produce an equivalent copy then the behaviour is undefined. But we can make our std::function more tolerant of such objects by ensuring we always copy from a const lvalue.

2018-05-09rs6000: Give an argument to every REG_CFA_REGISTER (PR85645)Segher Boessenkool2-3/+9
The one for the prologue mflr did not have any value set, which means use the SET that is in the insn pattern. This works fine, except when some late pass decides to replace the SET_SRC -- this changes the meaning of the REG_CFA_REGISTER! Such passes should not do these things, but let's be more explicit here, for extra robustness. It could be argued that this defaulting is a design misfeature (it does not save much space either, etc.) PR rtl-optimization/85645 * config/rs6000/rs6000.c (rs6000_emit_prologue_components): Put a SET in the REG_CFA_REGISTER note for LR, don't leave it empty.

2018-05-09shrink-wrap: Improve spread_components (PR85645)Segher Boessenkool2-3/+30
In the testcase for PR85645 we do a pretty dumb placement of the prologue/epilogue for the LR component: we place an epilogue for LR before a control flow split where one of the branches clobbers LR eventually, and the other does not. The branch that does clobber it will need a prologue again some time later. Because saving and restoring LR is a two step process---it needs to be moved via a GPR--- the backend emits CFI directives so that we get correct unwind information. But both regcprop and regrename do not properly handle such CFI directives leading to ICEs. Now, neither of the two branches needs to have LR restored at all, because both of the branches end up in an infinite loop. This patch makes spread_component return a boolean saying if anything was changed, and if so, it is called again. This obviously is finite (there is a finite number of basic blocks, each with a finite number of components, and spread_components can only assign more components to a block, never less). I also instrumented the code, and on a bootstrap+regtest spread_components made changes a maximum of two times. Interestingly though it made changes on two iterations in a third of the cases it did anything at all!

We should never change the destination of a REG_CFA_REGISTER, just like for insns with a REG_CFA_RESTORE, because we need to have the same control flow information on all branches that join.

2018-05-09Add clobbers around IFN_LOAD/STORE_LANESRichard Sandiford6-17/+105
We build up the input to IFN_STORE_LANES one vector at a time. In RTL, each of these vector assignments becomes a write to subregs of the form (subreg:VEC (reg:AGGR R)), where R is the eventual input to the store lanes instruction. The problem is that RTL isn't very good at tracking liveness when things are initialised piecemeal by subregs, so R tends to end up being live on all paths from the entry block to the store. This in turn leads to unnecessary spilling around calls, as well as to excess register pressure in vector loops. This patch adds gimple clobbers to indicate the liveness of the IFN_STORE_LANES variable and makes sure that gimple clobbers are expanded to rtl clobbers where useful. For consistency it also uses clobbers to mark the point at which an IFN_LOAD_LANES variable is no longer needed. 2018-05-08 Richard Sandiford <richard.sandiford@linaro.org> gcc/ * cfgexpand.c (expand_clobber): New function.
