At a certain point the parsing overhead of the headers dominate and +you start losing in gains. + +As such from this I've made the default 10 splits per file to allow for some +room for growth in the future without needing changes to the split amount. +Since 5-10 show roughly the same gains it means we can afford to double the +file sizes before we need to up the split amount. This can be controlled +by the configure parameter --with-matchpd-partitions=. + +At 10 splits the sizes of the files are: + + 1.2M gimple-match-1.cc + 490K gimple-match-2.cc + 459K gimple-match-3.cc + 462K gimple-match-4.cc + 466K gimple-match-5.cc + 690K gimple-match-6.cc + 517K gimple-match-7.cc + 693K gimple-match-8.cc +1011K gimple-match-9.cc + 490K gimple-match-10.cc + 210K gimple-match-auto.h + +The reason gimple-match-1.cc is so large is because it got allocated a very +large function: gimple_simplify_NE_EXPR. + +Because of these sporadically large functions the allocation to a split happens +based on the amount of data already written to a split instead of just a simple +round robin allocation (though the patch supports that too.). This means that +once gimple_simplify_NE_EXPR is allocated to gimple-match-1.cc nothing uses it +again until the rest of the files catch up. + +To support this split a new header file *-match-auto.h is generated to allow +the individual files to compile separately. + +Lastly for the auto generated files I use pragmas to silence the unused +predicate warnings instead of the previous Makefile way because I couldn't find +a way to set them without knowing the number of split files beforehand. + +Finally with this change, bootstrap time has dropped 8 minutes on AArch64. + +[1] https://gcc.gnu.org/legacy-ml/gcc-patches/2018-04/msg01125.html + +gcc/ChangeLog: + + PR bootstrap/84402 + * genmatch.cc (emit_func, SIZED_BASED_CHUNKS, get_out_file): New. + (decision_tree::gen): Accept list of files instead of single and update + to write function definition to header and main file. + (write_predicate): Likewise. + (write_header): Emit pragmas and new includes. + (main): Create file buffers and cleanup. + (showUsage, write_header_includes): New. + +(cherry picked from commit 703417a030b3d80f55ba1402adc3f1692d3631e5) +--- + gcc/genmatch.cc | 226 ++++++++++++++++++++++++++++++++++++++++-------- + 1 file changed, 190 insertions(+), 36 deletions(-) + +diff --git a/gcc/genmatch.cc b/gcc/genmatch.cc +index 665d7e2106ff..f80e4b972288 100644 +--- a/gcc/genmatch.cc ++++ b/gcc/genmatch.cc +@@ -183,6 +183,33 @@ fprintf_indent (FILE *f, unsigned int indent, const char *format, ...) + va_end (ap); + } + ++/* Like fprintf, but print to two files, one header one C implementation. */ ++FILE *header_file = NULL; ++ ++static void ++#if GCC_VERSION >= 4001 ++__attribute__((format (printf, 4, 5))) ++#endif ++emit_func (FILE *f, bool open, bool close, const char *format, ...) ++{ ++ va_list ap1, ap2; ++ if (header_file != NULL) ++ { ++ if (open) ++ fprintf (header_file, "extern "); ++ va_start (ap2, format); ++ vfprintf (header_file, format, ap2); ++ va_end (ap2); ++ if (close) ++ fprintf (header_file, ";\n"); ++ } ++ ++ va_start (ap1, format); ++ vfprintf (f, format, ap1); ++ va_end (ap1); ++ fputc ('\n', f); ++} ++ + static void + output_line_directive (FILE *f, location_t location, + bool dumpfile = false, bool fnargs = false) +@@ -217,6 +244,37 @@ output_line_directive (FILE *f, location_t location, + fprintf (f, "/* #line %d \"%s\" */\n", loc.line, loc.file); + } + ++/* Find the file to write into next.

The issue is that if the register used to +hold the lowpart of the destination is mentioned in the address of +the memory operand, the current define_insn_and_split unintentionally +clobbers it before reading the highpart. + +Hence, for the testcase, the incorrectly generated code looks like: + + salq $4, %rdi // calculate address + movq WHIRL_S+8(%rdi), %rdi // accidentally clobber addr + movq WHIRL_S(%rdi), %rbp // load (wrong) lowpart + +Traditionally, the textbook way to fix this would be to add an +explicit early clobber to the instruction's constraints. + + (define_insn_and_split "<insn>32di2_doubleword" +- [(set (match_operand:DI 0 "register_operand" "=r,r,r") ++ [(set (match_operand:DI 0 "register_operand" "=r,r,&r") + (any_rotate:DI (match_operand:DI 1 "nonimmediate_operand" "0,r,o") + (const_int 32)))] + +but unfortunately this currently generates significantly worse code, +due to a strange choice of reloads (effectively memcpy), which ends up +looking like: + + salq $4, %rdi // calculate address + movdqa WHIRL_S(%rdi), %xmm0 // load the double word in SSE reg. + movaps %xmm0, -16(%rsp) // store the SSE reg back to the stack + movq -8(%rsp), %rdi // load highpart + movq -16(%rsp), %rbp // load lowpart + +Note that reload's "&" doesn't distinguish between the memory being +early clobbered, vs the registers used in an addressing mode being +early clobbered. + +The fix proposed in this patch is to remove the third alternative, that +allowed offsetable memory as an operand, forcing reload to place the +operand into a register before the rotation. This results in: + + salq $4, %rdi + movq WHIRL_S(%rdi), %rax + movq WHIRL_S+8(%rdi), %rdi + movq %rax, %rbp + +I believe there's a more advanced solution, by swapping the order of +the loads (if first destination register is mentioned in the address), +or inserting a lea insn (if both destination registers are mentioned +in the address), but this fix is a minimal "safe" solution, that +should hopefully be suitable for backporting. + +2023-08-03 Roger Sayle <roger@nextmovesoftware.com> + +gcc/ChangeLog + PR target/110792 + * config/i386/i386.md (<any_rotate>ti3): For rotations by 64 bits + place operand in a register before gen_<insn>64ti2_doubleword. + (<any_rotate>di3): Likewise, for rotations by 32 bits, place + operand in a register before gen_<insn>32di2_doubleword. + (<any_rotate>32di2_doubleword): Constrain operand to be in register. + (<any_rotate>64ti2_doubleword): Likewise. + +gcc/testsuite/ChangeLog + PR target/110792 + * g++.target/i386/pr110792.C: New 32-bit C++ test case. + * gcc.target/i386/pr110792.c: New 64-bit C test case. + +(cherry picked from commit 790c1f60a5662b16eb19eb4b81922995863c7571) +--- + gcc/config/i386/i386.md | 18 ++++++++++++------ + gcc/testsuite/g++.target/i386/pr110792.C | 16 ++++++++++++++++ + gcc/testsuite/gcc.target/i386/pr110792.c | 18 ++++++++++++++++++ + 3 files changed, 46 insertions(+), 6 deletions(-) + create mode 100644 gcc/testsuite/g++.target/i386/pr110792.C + create mode 100644 gcc/testsuite/gcc.target/i386/pr110792.c + +diff --git a/gcc/config/i386/i386.md b/gcc/config/i386/i386.md +index f3a3305..a71e837 100644 +--- a/gcc/config/i386/i386.md ++++ b/gcc/config/i386/i386.md +@@ -14359,7 +14359,10 @@ + emit_insn (gen_ix86_<insn>ti3_doubleword + (operands[0], operands[1], operands[2]));
