From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/gcc.target/mips/branch-helper.h | 37 +++++++++++++++++++++++++++ 1 file changed, 37 insertions(+) create mode 100644 gcc/testsuite/gcc.target/mips/branch-helper.h (limited to 'gcc/testsuite/gcc.target/mips/branch-helper.h') diff --git a/gcc/testsuite/gcc.target/mips/branch-helper.h b/gcc/testsuite/gcc.target/mips/branch-helper.h new file mode 100644 index 000000000..85399be4c --- /dev/null +++ b/gcc/testsuite/gcc.target/mips/branch-helper.h @@ -0,0 +1,37 @@ +/* DN(X) generates 2**N copies of asm instruction X. */ +#define D0(X) X +#define D1(X) X "\n\t" X +#define D2(X) D1 (D1 (X)) +#define D3(X) D2 (D1 (X)) +#define D4(X) D2 (D2 (X)) +#define D5(X) D4 (D1 (X)) +#define D6(X) D4 (D2 (X)) +#define D7(X) D4 (D2 (D1 (X))) +#define D8(X) D4 (D4 (X)) +#define D9(X) D8 (D1 (X)) +#define D10(X) D8 (D2 (X)) +#define D11(X) D8 (D2 (D1 (X))) +#define D12(X) D8 (D4 (X)) +#define D13(X) D8 (D4 (D1 (X))) +#define D14(X) D8 (D4 (D2 (X))) + +/* Emit something that is 0x1fff8 bytes long, which is the largest + permissible range for non-MIPS16 forward branches. */ +#define OCCUPY_0x1fff8 \ + asm (D14 ("nop") "\n\t" \ + D13 ("nop") "\n\t" \ + D12 ("nop") "\n\t" \ + D11 ("nop") "\n\t" \ + D10 ("nop") "\n\t" \ + D9 ("nop") "\n\t" \ + D8 ("nop") "\n\t" \ + D7 ("nop") "\n\t" \ + D6 ("nop") "\n\t" \ + D5 ("nop") "\n\t" \ + D4 ("nop") "\n\t" \ + D3 ("nop") "\n\t" \ + D2 ("nop") "\n\t" \ + D1 ("nop")) + +/* Likewise emit something that is 0x1fffc bytes long. */ +#define OCCUPY_0x1fffc do { asm ("nop"); OCCUPY_0x1fff8; } while (0) -- cgit v1.2.3
