Subject: [PATCH 099/188] LoongArch: testsuite:Give up the detection of the
|
||
|
|
gcc.dg/fma-{3, 4, 6, 7}.c file.
|
||
|
|
|
||
|
|
On the LoongArch architecture, the above four test cases need to be waived
|
||
|
|
during testing. There are two situations:
|
||
|
|
|
||
|
|
1. The function of fma-{3,6}.c test is to find the value of c-a*b, but on
|
||
|
|
the LoongArch architecture, the function of the existing fnmsub instruction
|
||
|
|
is to find the value of -(a*b - c);
|
||
|
|
|
||
|
|
2. The function of fma-{4,7}.c test is to find the value of -(a*b)-c, but on
|
||
|
|
the LoongArch architecture, the function of the existing fnmadd instruction
|
||
|
|
is to find the value of -(a*b + c);
|
||
|
|
|
||
|
|
Through the analysis of the above two cases, there will be positive and
|
||
|
|
negative zero inequality.

gcc/testsuite/ChangeLog
|
||
|
|
|
||
|
|
* gcc.dg/fma-3.c: The intermediate file corresponding to the
|
||
|
|
function does not produce the corresponding FNMA symbol, so the test
|
||
|
|
rules should be skipped when testing.
|
||
|
|
* gcc.dg/fma-4.c: The intermediate file corresponding to the
|
||
|
|
function does not produce the corresponding FNMS symbol, so skip the
|
||
|
|
test rules when testing.
|
||
|
|
* gcc.dg/fma-6.c: The cause is the same as fma-3.c.
|
||
|
|
* gcc.dg/fma-7.c: The cause is the same as fma-4.c
