@ This test has a partner (ldr-pseudo-darwin.s) that contains matching @ tests for the ldr-pseudo on darwin targets. We need separate files @ because the syntax for switching sections and temporary labels differs @ between darwin and linux. Any tests added here should have a matching @ test added there. @RUN: llvm-mc -triple armv7-unknown-linux-gnueabi %s | FileCheck %s @RUN: llvm-mc -triple thumbv5-unknown-linux-gnueabi %s | FileCheck %s @RUN: llvm-mc -triple thumbv7-unknown-linux-gnueabi %s | FileCheck %s @ @ Check that large constants are converted to ldr from constant pool @ @ simple test .section b,"ax",%progbits @ CHECK-LABEL: f3: f3: ldr r0, =0x10001 @ CHECK: ldr r0, .Ltmp[[TMP0:[0-9]+]] @ loading multiple constants .section c,"ax",%progbits @ CHECK-LABEL: f4: f4: ldr r0, =0x10002 @ CHECK: ldr r0, .Ltmp[[TMP1:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 ldr r0, =0x10003 @ CHECK: ldr r0, .Ltmp[[TMP2:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 @ TODO: the same constants should have the same constant pool location .section d,"ax",%progbits @ CHECK-LABEL: f5: f5: ldr r0, =0x10004 @ CHECK: ldr r0, .Ltmp[[TMP3:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 ldr r0, =0x10004 @ CHECK: ldr r0, .Ltmp[[TMP4:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 @ a section defined in multiple pieces should be merged and use a single constant pool .section e,"ax",%progbits @ CHECK-LABEL: f6: f6: ldr r0, =0x10006 @ CHECK: ldr r0, .Ltmp[[TMP5:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 .section f, "ax", %progbits @ CHECK-LABEL: f7: f7: adds r0, r0, #1 adds r0, r0, #1 adds r0, r0, #1 .section e, "ax", %progbits @ CHECK-LABEL: f8: f8: adds r0, r0, #1 ldr r0, =0x10007 @ CHECK: ldr r0, .Ltmp[[TMP6:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 @ @ Check that symbols can be loaded using ldr pseudo @ @ load an undefined symbol .section g,"ax",%progbits @ CHECK-LABEL: f9: f9: ldr r0, =foo @ CHECK: ldr r0, .Ltmp[[TMP7:[0-9]+]] @ load a symbol from another section .section h,"ax",%progbits @ CHECK-LABEL: f10: f10: ldr r0, =f5 @ CHECK: ldr r0, .Ltmp[[TMP8:[0-9]+]] @ load a symbol from the same section .section i,"ax",%progbits @ CHECK-LABEL: f11: f11: ldr r0, =f12 @ CHECK: ldr r0, .Ltmp[[TMP9:[0-9]+]] @ CHECK-LABEL: f12: f12: adds r0, r0, #1 adds r0, r0, #1 .section j,"ax",%progbits @ mix of symbols and constants @ CHECK-LABEL: f13: f13: adds r0, r0, #1 adds r0, r0, #1 ldr r0, =0x101 @ CHECK: ldr r0, .Ltmp[[TMP10:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 ldr r0, =bar @ CHECK: ldr r0, .Ltmp[[TMP11:[0-9]+]] adds r0, r0, #1 adds r0, r0, #1 @ @ Check for correct usage in other contexts @ @ usage in macro .macro useit_in_a_macro ldr r0, =0x10008 ldr r0, =baz .endm .section k,"ax",%progbits @ CHECK-LABEL: f14: f14: useit_in_a_macro @ CHECK: ldr r0, .Ltmp[[TMP12:[0-9]+]] @ CHECK: ldr r0, .Ltmp[[TMP13:[0-9]+]] @ usage with expressions .section l, "ax", %progbits @ CHECK-LABEL: f15: f15: ldr r0, =0x10001+8 @ CHECK: ldr r0, .Ltmp[[TMP14:[0-9]+]] adds r0, r0, #1 ldr r0, =bar+4 @ CHECK: ldr r0, .Ltmp[[TMP15:[0-9]+]] adds r0, r0, #1 @ @ Constant Pools @ @ CHECK: .section b,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP0]] @ CHECK: .long 65537 @ CHECK: .section c,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP1]] @ CHECK: .long 65538 @ CHECK: .Ltmp[[TMP2]] @ CHECK: .long 65539 @ CHECK: .section d,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP3]] @ CHECK: .long 65540 @ CHECK: .Ltmp[[TMP4]] @ CHECK: .long 65540 @ CHECK: .section e,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP5]] @ CHECK: .long 65542 @ CHECK: .Ltmp[[TMP6]] @ CHECK: .long 65543 @ Should not switch to section because it has no constant pool @ CHECK-NOT: .section f,"ax",%progbits @ CHECK: .section g,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP7]] @ CHECK: .long foo @ CHECK: .section h,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP8]] @ CHECK: .long f5 @ CHECK: .section i,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP9]] @ CHECK: .long f12 @ CHECK: .section j,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP10]] @ CHECK: .long 257 @ CHECK: .Ltmp[[TMP11]] @ CHECK: .long bar @ CHECK: .section k,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP12]] @ CHECK: .long 65544 @ CHECK: .Ltmp[[TMP13]] @ CHECK: .long baz @ CHECK: .section l,"ax",%progbits @ CHECK: .align 2 @ CHECK: .Ltmp[[TMP14]] @ CHECK: .long 65545 @ CHECK: .Ltmp[[TMP15]] @ CHECK: .long bar+4
