  9. [BPF] add new intrinsics preserve_{array,union,struct}_access_index For background of BPF CO-RE project, please refer to http://vger.kernel.org/bpfconf2019.html In summary, BPF CO-RE intends to compile bpf programs adjustable on struct/union layout change so the same program can run on multiple kernels with adjustment before loading based on native kernel structures. In order to do this, we need keep track of GEP(getelementptr) instruction base and result debuginfo types, so we can adjust on the host based on kernel BTF info. Capturing such information as an IR optimization is hard as various optimization may have tweaked GEP and also union is replaced by structure it is impossible to track fieldindex for union member accesses. Three intrinsic functions, preserve_{array,union,struct}_access_index, are introducted. addr = preserve_array_access_index(base, index, dimension) addr = preserve_union_access_index(base, di_index) addr = preserve_struct_access_index(base, gep_index, di_index) here, base: the base pointer for the array/union/struct access. index: the last access index for array, the same for IR/DebugInfo layout. dimension: the array dimension. gep_index: the access index based on IR layout. di_index: the access index based on user/debuginfo types. For example, for the following example, $ cat test.c struct sk_buff { int i; int b1:1; int b2:2; union { struct { int o1; int o2; } o; struct { char flags; char dev_id; } dev; int netid; } u[10]; }; static int (*bpf_probe_read)(void *dst, int size, const void *unsafe_ptr) = (void *) 4; #define _(x) (__builtin_preserve_access_index(x)) int bpf_prog(struct sk_buff *ctx) { char dev_id; bpf_probe_read(&dev_id, sizeof(char), _(&ctx->u[5].dev.dev_id)); return dev_id; } $ clang -target bpf -O2 -g -emit-llvm -S -mllvm -print-before-all \ test.c >& log The generated IR looks like below: ... define dso_local i32 @bpf_prog(%struct.sk_buff*) #0 !dbg !15 { %2 = alloca %struct.sk_buff*, align 8 %3 = alloca i8, align 1 store %struct.sk_buff* %0, %struct.sk_buff** %2, align 8, !tbaa !45 call void @llvm.dbg.declare(metadata %struct.sk_buff** %2, metadata !43, metadata !DIExpression()), !dbg !49 call void @llvm.lifetime.start.p0i8(i64 1, i8* %3) #4, !dbg !50 call void @llvm.dbg.declare(metadata i8* %3, metadata !44, metadata !DIExpression()), !dbg !51 %4 = load i32 (i8*, i32, i8*)*, i32 (i8*, i32, i8*)** @bpf_probe_read, align 8, !dbg !52, !tbaa !45 %5 = load %struct.sk_buff*, %struct.sk_buff** %2, align 8, !dbg !53, !tbaa !45 %6 = call [10 x %union.anon]* @llvm.preserve.struct.access.index.p0a10s_union.anons.p0s_struct.sk_buffs( %struct.sk_buff* %5, i32 2, i32 3), !dbg !53, !llvm.preserve.access.index !19 %7 = call %union.anon* @llvm.preserve.array.access.index.p0s_union.anons.p0a10s_union.anons( [10 x %union.anon]* %6, i32 1, i32 5), !dbg !53 %8 = call %union.anon* @llvm.preserve.union.access.index.p0s_union.anons.p0s_union.anons( %union.anon* %7, i32 1), !dbg !53, !llvm.preserve.access.index !26 %9 = bitcast %union.anon* %8 to %struct.anon.0*, !dbg !53 %10 = call i8* @llvm.preserve.struct.access.index.p0i8.p0s_struct.anon.0s( %struct.anon.0* %9, i32 1, i32 1), !dbg !53, !llvm.preserve.access.index !34 %11 = call i32 %4(i8* %3, i32 1, i8* %10), !dbg !52 %12 = load i8, i8* %3, align 1, !dbg !54, !tbaa !55 %13 = sext i8 %12 to i32, !dbg !54 call void @llvm.lifetime.end.p0i8(i64 1, i8* %3) #4, !dbg !56 ret i32 %13, !dbg !57 } !19 = distinct !DICompositeType(tag: DW_TAG_structure_type, name: "sk_buff", file: !3, line: 1, size: 704, elements: !20) !26 = distinct !DICompositeType(tag: DW_TAG_union_type, scope: !19, file: !3, line: 5, size: 64, elements: !27) !34 = distinct !DICompositeType(tag: DW_TAG_structure_type, scope: !26, file: !3, line: 10, size: 16, elements: !35) Note that @llvm.preserve.{struct,union}.access.index calls have metadata llvm.preserve.access.index attached to instructions to provide struct/union debuginfo type information.

The "%8 = ..." represents union member "dev" with index 1 for DI layout. . The "%10 = ..." represents struct member "dev_id" with index 1 for both IR and DI layout. Basically, traversing the use-def chain recursively for the 3rd argument of bpf_probe_read() and examining all preserve_*_access_index calls, the debuginfo struct/union/array access index can be achieved. The intrinsics also contain enough information to regenerate codes for IR layout. For array and structure intrinsics, the proper GEP can be constructed. For union intrinsics, replacing all uses of "addr" with "base" should be enough. The test case ThinLTO/X86/lazyload_metadata.ll is adjusted to reflect the new addition of the metadata.

[MachinePipeliner] Fix Phi refers to Phi in same stage in 1st epilogue

Summary:
This is exposed by functional testing on PowerPC.
In some pipelined loops, Phi refer to phi did not get value defined by
the Phi, hence getting wrong value later.

As the comment mentioned, we should "use the value defined by the Phi,
unless we're generating the firstepilog and the Phi refers to a Phi
in a different stage.", so Phi refering to same stage Phi should use
the value defined by the Phi here.

[BPF] add new intrinsics preserve_{array,union,struct}_access_index

For background of BPF CO-RE project, please refer to
  http://vger.kernel.org/bpfconf2019.html
In summary, BPF CO-RE intends to compile bpf programs
adjustable on struct/union layout change so the same
program can run on multiple kernels with adjustment
before loading based on native kernel structures.

In order to do this, we need keep track of GEP(getelementptr)
instruction base and result debuginfo types, so we
can adjust on the host based on kernel BTF info.
Capturing such information as an IR optimization is hard
as various optimization may have tweaked GEP and also
union is replaced by structure it is impossible to track
fieldindex for union member accesses.

Three intrinsic functions, preserve_{array,union,struct}_access_index,
are introducted.
  addr = preserve_array_access_index(base, index, dimension)
  addr = preserve_union_access_index(base, di_index)
  addr = preserve_struct_access_index(base, gep_index, di_index)
here,
  base: the base pointer for the array/union/struct access.
  index: the last access index for array, the same for IR/DebugInfo layout.
  dimension: the array dimension.
  gep_index: the access index based on IR layout.
  di_index: the access index based on user/debuginfo types.

For example, for the following example,
  $ cat test.c
  struct sk_buff {
     int i;
     int b1:1;
     int b2:2;
     union {
       struct {
         int o1;
         int o2;
       } o;
       struct {
         char flags;
         char dev_id;
       } dev;
       int netid;
     } u[10];
  };

  static int (*bpf_probe_read)(void *dst, int size, const void *unsafe_ptr)
      = (void *) 4;

  #define _(x) (__builtin_preserve_access_index(x))

  int bpf_prog(struct sk_buff *ctx) {
    char dev_id;
    bpf_probe_read(&dev_id, sizeof(char), _(&ctx->u[5].dev.dev_id));
    return dev_id;
  }
  $ clang -target bpf -O2 -g -emit-llvm -S -mllvm -print-before-all \
    test.c >& log

The generated IR looks like below:

  ...
  define dso_local i32 @bpf_prog(%struct.sk_buff*) #0 !dbg !15 {
    %2 = alloca %struct.sk_buff*, align 8
    %3 = alloca i8, align 1
    store %struct.sk_buff* %0, %struct.sk_buff** %2, align 8, !tbaa !45
    call void @llvm.dbg.declare(metadata %struct.sk_buff** %2, metadata !43, metadata !DIExpression()), !dbg !49
    call void @llvm.lifetime.start.p0i8(i64 1, i8* %3) #4, !dbg !50
    call void @llvm.dbg.declare(metadata i8* %3, metadata !44, metadata !DIExpression()), !dbg !51
    %4 = load i32 (i8*, i32, i8*)*, i32 (i8*, i32, i8*)** @bpf_probe_read, align 8, !dbg !52, !tbaa !45
    %5 = load %struct.sk_buff*, %struct.sk_buff** %2, align 8, !dbg !53, !tbaa !45
    %6 = call [10 x %union.anon]* @llvm.preserve.struct.access.index.p0a10s_union.anons.p0s_struct.sk_buffs(
         %struct.sk_buff* %5, i32 2, i32 3), !dbg !53, !llvm.preserve.access.index !19
    %7 = call %union.anon* @llvm.preserve.array.access.index.p0s_union.anons.p0a10s_union.anons(
         [10 x %union.anon]* %6, i32 1, i32 5), !dbg !53
    %8 = call %union.anon* @llvm.preserve.union.access.index.p0s_union.anons.p0s_union.anons(
         %union.anon* %7, i32 1), !dbg !53, !llvm.preserve.access.index !26
    %9 = bitcast %union.anon* %8 to %struct.anon.0*, !dbg !53
    %10 = call i8* @llvm.preserve.struct.access.index.p0i8.p0s_struct.anon.0s(
         %struct.anon.0* %9, i32 1, i32 1), !dbg !53, !llvm.preserve.access.index !34
    %11 = call i32 %4(i8* %3, i32 1, i8* %10), !dbg !52
    %12 = load i8, i8* %3, align 1, !dbg !54, !tbaa !55
    %13 = sext i8 %12 to i32, !dbg !54
    call void @llvm.lifetime.end.p0i8(i64 1, i8* %3) #4, !dbg !56
    ret i32 %13, !dbg !57
  }

  !19 = distinct !DICompositeType(tag: DW_TAG_structure_type, name: "sk_buff", file: !3, line: 1, size: 704, elements: !20)
  !26 = distinct !DICompositeType(tag: DW_TAG_union_type, scope: !19, file: !3, line: 5, size: 64, elements: !27)
  !34 = distinct !DICompositeType(tag: DW_TAG_structure_type, scope: !26, file: !3, line: 10, size: 16, elements: !35)

Note that @llvm.preserve.{struct,union}.access.index calls have metadata llvm.preserve.access.index
attached to instructions to provide struct/union debuginfo type information.

For &ctx->u[5].dev.dev_id,
  . The "%6 = ..." represents struct member "u" with index 2 for IR layout and index 3 for DI layout.
  . The "%7 = ..." represents array subscript "5".
  . The "%8 = ..." represents union member "dev" with index 1 for DI layout.
  . The "%10 = ..." represents struct member "dev_id" with index 1 for both IR and DI layout.

Basically, traversing the use-def chain recursively for the 3rd argument of bpf_probe_read() and
examining all preserve_*_access_index calls, the debuginfo struct/union/array access index
can be achieved.

The intrinsics also contain enough information to regenerate codes for IR layout.
For array and structure intrinsics, the proper GEP can be constructed.
For union intrinsics, replacing all uses of "addr" with "base" should be enough.

The test case ThinLTO/X86/lazyload_metadata.ll is adjusted to reflect the
new addition of the metadata.

Summary

  1. Use `ln -n` to prevent forming a symlink cycle, instead of rm'ing the source This is a better fix for the problem fixed in r334972. Also remove the rm'ing of the symlink destination that was there to clean up the bots -- it's over a year later, bots should be happy now. Differential Revision: https://reviews.llvm.org/D64301
