Stefanos Kornilios Mitsis Poiitidis 50b5ad5762 Merge pull request #1070 from Sonicadvance1/remove_warnings 
Remove most warnings in FEX again
 2021-06-14 10:12:03 +03:00
Lioncash d08189c3ed Passes: Log out errors and warnings through a format specifier 
Passing in the string directly through the format string input can
unintentionally cause the output string to be interpreted as a format
string.

We can specify a separate format string to ensure it always prints
without any potential mangling.

Lioncash 2ad9ced80a Passes: Replace <iostream> header with narrower equivalents 
<iostream> injects a static constructor in translation units that
include it, even if its facilities aren't used.

We can make use of <sstream> to avoid needing to execute those on
startup.
 2021-06-11 22:24:45 -04:00
Lioncash 120ba3d171 PassManager: std::move exit handler function 
Avoids allocations if the internal std::function buffer ever happens to
be large enough to warrant it.
 2021-06-11 22:05:17 -04:00
Lioncash 6084bdf982 Passes: Return by unique_ptr where applicable 
Same behavior, but makes the ownership intentions explicit in the
interface.
 2021-06-11 22:05:15 -04:00
Lioncash b6edc8dc53 RegisterAllocationPass: Prevent leaks in BucketList 
release() relinquishes control of the allocated memory, but doesn't
deallocate it. We need reset() for this.
 2021-06-11 17:49:56 -04:00
Ryan Houdek 0f1a41154d RAPass: Remove warning 2021-06-10 14:56:39 -07:00

Ryan Houdek f94ce4c95b IRCompaction: Remove warning 2021-06-10 14:56:17 -07:00
Lioncash 9ed0572fa4 IRParser: Make use of unique_ptr for Parse() 
Communicates ownership semantics to the user of the API a little better,
and makes it harder to accidentally leak memory.
 2021-06-09 21:00:30 -04:00
Lioncash 00b0222129 IRParser: Make use of find character overloads 
Results in a tiny bit better codegen. May as well, since the changes are
essentially 'free'.
 2021-06-09 21:00:30 -04:00
Lioncash 32cc98856f IRParser: Add missing default return in DecodeErrorToString() 
Prevents undefined behavior in the event anything actually reaches this.
 2021-06-09 21:00:30 -04:00
Lioncash dee7441795 IRParser: Make input string to DecodeValue a const reference 
No specializations modify this, and even if they did, it would be a
little confusing to statefully modify the string this way.

Instead, we can make it read-only.
 2021-06-09 21:00:29 -04:00
Ryan Houdek 5ac9b45528 Merge pull request #1059 from Sonicadvance1/fix_rounding 
Fixes floating point conversion rounding bugs
 2021-06-09 17:58:35 -07:00
Ryan Houdek 104fabc11f Merge pull request #1061 from lioncash/dump 
IRParser: Make use of fmt where applicable
 2021-06-08 07:10:10 -07:00
Ryan Houdek d57a034220 Fixes floating point conversion rounding bugs 
When floats and doubles were converting to integers we weren't doing the correct transformation.
AArch64 provides direct ops for all four of the op types. So lets use them
  - f32 -> int64
  - f32 -> int32
  - f64 -> int64
  - f64 -> int32

Doesn't fully fix the case of overflow for AArch64 since overflow behaviour is different.
x86 returns 0x8000'0000 or 0x8000'0000'0000'0000 while AArch64 saturates to the maximum signed
integers. Can't work around that without checking overflow flags.

This does solve the typical case though.
Fixes audio problems in all FMod games.

Lioncash 05ee4c363b IRParser: Make use of fmt where applicable 2021-06-08 09:47:13 -04:00
Lioncash 6f2f4a9bc0 IRDumper: Make use of std::string_view over std::string where applicable 
Same behavior, but with a smaller footprint (and the ability to be
constant data).
 2021-06-08 09:36:59 -04:00
Ryan Houdek 1b06a06a4e Makes RoundType a unique type 
This allows us to have the IRDumper have unique output for the type
 2021-06-08 02:44:40 -07:00
Ryan Houdek 8b7a7e91c9 Implements new IR ops 
Adds VBic, VUMinV, VPopcount, VUnZip, VUnZip2, VDupElement, Vector_FToI, and VUABDL

We will need these for the SSE4.1 ops
 2021-06-08 02:44:39 -07:00
Lioncash 18e0f2636f General: Make use of the <bit> header where applicable 
Since C++20, a bunch of bit manipulation functions finally have a common
interface, so lets make use of those
 2021-06-07 08:16:51 -04:00
Lioncash 58272ffc47 ConstProp: Separate out constituent chunks of const prop 
Makes it nicer to find where each part of the pass is, and also see how
the pass is operating at a high level.
 2021-06-05 16:52:03 -04:00
Lioncash 262389f4ea ConstProp: Mark internal functions as static 
Allows them to have internal linkage.
 2021-06-05 15:25:35 -04:00
Lioncash 35f3777797 IRParser: Make use of insert_or_assign where applicable 
Avoids some minor potential default constructions that get overwritten
immediately.
 2021-06-05 06:43:17 -04:00
Lioncash d73b79470e IRParser: Mark parameter of CheckPrintError as a const reference 
Def is only ever accessed to read members, so we can signify to the
reader to not expect it to be modified.
 2021-06-05 06:43:16 -04:00
Lioncash 676d9cb665 IRParser: std::move elements where advantageous 
e.g. LineDefinitions are moderately beefy, they contain
two strings and a vector of strings among other things,
so we can move instances into their containing vector to avoid some
allocation churn.
 2021-06-05 06:43:13 -04:00
Lioncash 993b4513d9 IRParser: Convert array of std::string over to array of std::string_view 
Same behavior, but allows the arrays to be constexpr (and use less
space; 16 bytes vs 32 bytes per element).

Stefanos Kornilios Mitsis Poiitidis 331549c64a RLSE: Use Constant, not inline constant, let ConstProp generate all inline consts 2021-05-01 09:40:50 +03:00

Ryan Houdek bab5927931 Merge pull request #981 from Sonicadvance1/optimize_long_divide 
Adds Long Divide removal pass
 2021-04-26 23:48:50 -07:00
Ryan Houdek 6255eba524 Memory layout optimizations 
Some of these memory layouts weren't optimal for ARM loading.
This is now significantly improved
 2021-04-26 23:48:22 -07:00
Ryan Houdek 04e0baadc6 Changes LogMan assert to defines 
C++ no-op functions can't optimize out the predicate arguments in all cases.
This was causing a problem where zero cost assertions weren't actually zero cost.

The only way to resolve this is to actually use macros sadly enough.

This will give a fairly hefty performance uplift with anything operating on IR.

Stefanos Kornilios Mitsis Poiitidis b45b7c3441 IR: Remove Entry from OP_HEADER, pass as parameter to CompileCode 2021-04-25 13:15:23 +03:00
Ryan Houdek 520dfd7edf Adds Long Divide removal pass 
If the long divides don't have anything in the upper bits then they can be optimized away.
Teeworlds, SuperTuxKart, and RRootage were between 50%-55% getting removed

Lioncache 434a74a88a CMakeLists: Flag unannotated implicit fallthrough as an error 
Prevents a class of sneaky logic bugs from slipping through into the
codebase.

This also resolves a case of such a bug within the Decorder's ReadData()
where all 3 byte reads would be performed as if they were a 4 byte read.

Ryan Houdek 15dd70487f Removes legacy difference between FEX config env variable and enum names 2021-03-29 00:26:11 -07:00
Ryan Houdek 43ddba4e82 Adds support for CPUID leafs 
Leafs come from ECX but only some CPUID functions support this.
This adds the initial infrastructure but doesn't yet add support for the CPUID functions to consume the leaf.

Stefanos Kornilios Mitsis Poiitidis 971740991b RCLSE: Invalidate around OP_SYSCALLs, Syscalls might read the context and need the latest version of it
