-When enabled the PHI handing for COND_EXPR, we need to insert the gcall
-to replace the PHI node. Unfortunately, I made a mistake that insert
-the gcall to before the last stmt of the bb. See below gimple, the PHI
-is located at no.1 but we insert the gcall (aka no.9) to the end of
-the bb. Then the use of _9 in no.2 will have no def and will trigger
-ICE when verify_ssa.
-
- 1. # _9 = PHI <_3(4), 18446744073709551615(3)> // The PHI node to be deleted.
- 2. prephitmp_36 = (char *) _9;
- 3. buf.write_base = string_13(D);
- 4. buf.write_ptr = string_13(D);
- 5. buf.write_end = prephitmp_36;
- 6. buf.written = 0;
- 7. buf.mode = 3;
- 8. _7 = buf.write_end;
- 9. _9 = .SAT_ADD (string.0_2, maxlen_15(D)); // Insert gcall to last bb by mistake
-
-This patch would like to insert the gcall to before the start of the bb
-stmt. To ensure the possible use of PHI_result will have a def exists.
-After this patch the above gimple will be:
-
- 0. _9 = .SAT_ADD (string.0_2, maxlen_15(D)); // Insert gcall to start bb by mistake
- 1. # _9 = PHI <_3(4), 18446744073709551615(3)> // The PHI node to be deleted.
- 2. prephitmp_36 = (char *) _9;
- 3. buf.write_base = string_13(D);
- 4. buf.write_ptr = string_13(D);
- 5. buf.write_end = prephitmp_36;
- 6. buf.written = 0;
- 7. buf.mode = 3;
- 8. _7 = buf.write_end;
-
-The below test suites are passed for this patch:
-* The rv64gcv fully regression test with newlib.
-* The rv64gcv build with glibc.
-* The x86 regression test with newlib.
-* The x86 bootstrap test with newlib.

- PR target/115387
-
-gcc/ChangeLog:
-
- * tree-ssa-math-opts.cc (math_opts_dom_walker::after_dom_children): Take
- the gsi of start_bb instead of last_bb.
-
-gcc/testsuite/ChangeLog:
-
- * gcc.target/riscv/pr115387-1.c: New test.
- * gcc.target/riscv/pr115387-2.c: New test.
