re PR rtl-optimization/61926 (const-anchor optimisation is sensitive to ordering)
gcc/testsuite/
PR rtl-optimization/61926
* gcc.target/mips/const-anchor-1.c, gcc.target/mips/const-anchor-2.c:
Reverse argument order.
* gcc.target/mips/const-anchor-3.c, gcc.target/mips/const-anchor-4.c:
New XFAILed tests that match the original order.
