4Subject: [PATCH] Replace MCTargetOptionsCommandFlags.inc and CommandFlags.inc
5 by runtime registration
6
7MCTargetOptionsCommandFlags.inc and CommandFlags.inc are headers which contain
8cl::opt with static storage.
9These headers are meant to be incuded by tools to make it easier to parametrize
10codegen/mc.
11
12However, these headers are also included in at least two libraries: lldCommon
13and handle-llvm. As a result, when creating DYLIB, clang-cpp holds a reference
14to the options, and lldCommon holds another reference. Linking the two in a
15single executable, as zig does[0], results in a double registration.
16
17This patch explores an other approach: the .inc files are moved to regular
18files, and the registration happens on-demand through static declaration of
19options in the constructor of a static object.

4Subject: [PATCH] Basic Block Sections Support.
5
6This is the first in a series of patches to enable Basic Block Sections
7in LLVM.
8
9We introduce a new compiler option, -fbasicblock-sections=, which places every
10basic block in a unique ELF text section in the object file along with a
11symbol labeling the basic block. The linker can then order the basic block
12sections in any arbitrary sequence which when done correctly can encapsulate
13block layout, function layout and function splitting optimizations. However,
14there are a couple of challenges to be addressed for this to be feasible:
15
161) The compiler must not allow any implicit fall-through between any two
17 adjacent basic blocks as they could be reordered at link time to be
18 non-adjacent. In other words, the compiler must make a fall-through
19 between adjacent basic blocks explicit by retaining the direct jump
20 instruction that jumps to the next basic block. These branches can only
21 be removed later by the linker after the blocks have been reordered.
222) All inter-basic block branch targets would now need to be resolved by
23 the linker as they cannot be calculated during compile time. This is
24 done using static relocations which bloats the size of the object files.
25 Further, the compiler tries to use short branch instructions on some ISAs
26 for branch offsets that can be accommodated in one byte. This is not
27 possible with basic block sections as the offset is not determined at
28 compile time, and long branch instructions have to be used everywhere.
293) Each additional section bloats object file sizes by tens of bytes. The
30 number of basic blocks can be potentially very large compared to the
31 size of functions and can bloat object sizes significantly. Option
32 fbasicblock-sections= also takes a file path which can be used to
33 specify a subset of basic blocks that needs unique sections to keep
34 the bloats small.
354) Debug Info and CFI need special handling and will be presented as
36 separate patches.
37
38Basic Block Labels
39
40With -fbasicblock-sections=labels, or when a basic block is placed in a
41unique section, it is labelled with a symbol. This allows easy mapping of
42virtual addresses from PMU profiles back to the corresponding basic blocks.
43Since the number of basic blocks is large, the labeling bloats the symbol
44table sizes and the string table sizes significantly. While the binary size
45does increase, it does not affect performance as the symbol table is not
46loaded in memory during run-time. The string table size bloat is kept very
47minimal using a unary naming scheme that uses string suffix compression.
48The basic blocks for function foo are named "a.BB.foo", "aa.BB.foo", ...
49This turns out to be very good for string table sizes and the bloat in the
50string table size for a very large binary is ~8 %. The naming also allows
51using the --symbol-ordering-file option in LLD to arbitrarily reorder the
52sections.
