You simply need to open a GitLab account, add your job (probably in .gitlab-ci.d/buildtest.yml) and push your branch to test it. > Reviewed-by: Aleksandar Rikalo <aleksandar.rikalo@syrmia.com> > Signed-off-by: Filip Vidojevic <filip.vidojevic@syrmia.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> > --- > target/mips/tcg/translate.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/target/mips/tcg/translate.c b/target/mips/tcg/translate.c > index 797eba4434..2d0a723061 100644 > --- a/target/mips/tcg/translate.c > +++ b/target/mips/tcg/translate.c > @@ -21137,7 +21137,7 @@ static int > decode_nanomips_32_48_opc(CPUMIPSState *env, DisasContext *ctx) > extract32(ctx->opcode, 0, 1) << 13; > > gen_compute_branch_nm(ctx, OPC_BPOSGE32, 4, -1, -2, > - imm); > + imm << 1); > } > break; > default: > -- > 2.25.1
